447 313 10 15 20 25 30 genom den transparenta skivan. Det reflekterade ljuset får genom interferens- fenomen olika intensitet beroende på fran vilket parti av reliefen det kommer. 447 313 10 15 20 25 30 through the transparent disc. Through reflected interference, the reflected light has different intensities depending on which part of the relief it comes from.
Det är ocksa känt att göra ett lagringsmedium av i stort sett samma slag skrivbart. I ett sådant fall kan man bränna in hal i lagringsmediet med hjälp av fokuserat ljus fran lasern som da drivs med hög effekt. Vid läsning av informationen används en lägre ljuseffekt som ej påverkar lagringsmediet. Vid tillverkningen av lagringsmediet utnyttjas oftast samma teknik som ovan i fallet med fast information för att åstadkomma fasta spar användbara för positionering och fokusering av ljusfläcken. Över dessa spår läggs ett tunt skikt i vilket hälen bränns in. Exempel hârpa och ytterligare metoder för optisk datalagring finns i Vaccum Science and Technology Vol 18, nr 1 Jan/F eb 1981.It is also known to make a storage medium of substantially the same type writable. In such a case, one can burn sludge into the storage medium with the help of focused light from the laser, which is then operated with high power. When reading the information, a lower light effect is used that does not affect the storage medium. In the manufacture of the storage medium, the same technology as above is usually used in the case of fixed information to provide fixed savings useful for positioning and focusing the light spot. A thin layer is laid over these grooves in which the heel is burned. Examples of harpsichord and additional methods for optical data storage can be found in Vaccum Science and Technology Vol 18, no. 1 Jan / F eb 1981.
REDOGÜRELSE FÖR UPPFINNINGEN l manga sammanhang har man behov av ett litet, lättransporterat datamedium som rymmer en stor datamëngd. Exempel härpå är personliga sjukjournaler, identitetskort som skall ge kortinnehavaren tillträde till lokaler, databaser etc.SUMMARY OF THE INVENTION In many contexts, there is a need for a small, easily transported data medium that holds a large amount of data. Examples of this are personal medical records, identity cards that are to give the cardholder access to premises, databases, etc.
Ett krav är ocksa att läsaren och, i de fall informationsinnehållet skall kunna förändras, även skrivutrustningen skall vara enkel och billig. Det har visat sig att ett kort av det standardiserade kreditkortsformatet är idealiskt som databärare när det gäller formatet. Tyvärr blir de läsorgan som används för att läsa de remsformiga databärande omradena av magnetisk eller optisk typ som används i de ovan beskrivna databärande korten komplicerade speciellt om informationen är tätt packad.It is also a requirement that the reader and, in cases where the information content can be changed, the writing equipment must also be simple and cheap. It has been found that a card of the standardized credit card format is ideal as a data carrier in terms of format. Unfortunately, the reading means used to read the strip-shaped data-bearing areas of magnetic or optical type used in the above-described data-bearing cards become complicated especially if the information is tightly packed.
De runda skivor som används för optisk lagring av ljud-(CD-skívan) och videosignaler och som databärare accepteras inte som ett lätt transportabelt datamedium på grund av sin cirkulära form. De är vidare avsedda för mycket stora datamängder och läs- och skrivorgan maste vara försedda med mekaniska anordningar för radiell avsökning av skivan. _ ._ Det har visat sig att för de flesta ändamål kan man nöja sig med en ínformationsmängd < 2 Mbyte. Enligt uppfinningen är det möjligt att i ett sådant fall använda ett företrädesvis rektangulärt kort försett med ett område avsett för registrering av data på optisk väg i form av markeringar vilka 10 15 20 25 447 313 modifierar egenskaperna hos det reflekterade ljuset fran en mot omradet infallande ljusstrale. Uppfinningen kännetecknas av att detta omrâde är ut- format som en cirkulär ring vars ringbredd är mycket mindre än ringdiarnetern.The round discs used for optical storage of audio (CD) and video signals and as data carriers are not accepted as an easily transportable data medium due to their circular shape. They are further intended for very large amounts of data and reading and writing means must be provided with mechanical devices for radial scanning of the disc. It has been shown that for most purposes, an amount of information <2 Mbyte can be satisfied. According to the invention, it is possible in such a case to use a preferably rectangular card provided with an area intended for recording data by optical means in the form of markings which modify the properties of the reflected light from a light beam incident on the area. . The invention is characterized in that this area is designed as a circular ring whose ring width is much smaller than the ring diurner.
Med nu tillgänglig optisk lagringsteknik kan man med en ringbredd pa ca 0,3 mm och en diameter pa ca 50 mm lagra ca 2 Mbyte i de ca 150 spår som ryms inom den angivna ringbredden.With the now available optical storage technology, with a ring width of approx. 0.3 mm and a diameter of approx. 50 mm, it is possible to store approx. 2 Mbytes in the approx. 150 grooves that fit within the specified ring width.
FIGURBESKRIVNING Uppfinningen skall närmare beskrivas i anslutning till bifogade figurer där Fig l och 2 visar tva utföringsformer av databärare, F ig 3 ett tvärsnitt genom en känd databârare och Fig 4 schematiskt visar en läs- och/ eller skrivanordning.DESCRIPTION OF THE FIGURES The invention will be described in more detail in connection with the accompanying figures, in which Figs. 1 and 2 show two embodiments of data carriers, Fig. 3 a cross-section through a known data carrier and Fig. 4 schematically shows a reading and / or writing device.
FÖREDRAGEN uTFöRrNcsFoRM Den i Fig 1 visade databäraren l utgörs av ett plastkort 1 lämpligen med det av ISO standardiserade formatet ca 54 x 86 mm. I kortytan finns inlagt ett smalt ringformat informationsbärande område 2. Detta omrâde rymmer t ex ett spiralspar av det slag som beskrivits i den ovan nämnda artikeln i Philips Technical Review men avsett för skrivning. Sparat som schematiskt visas i F ig 3 i ett genomskuret perspektiv består av ett genomskinligt basmaterial 5 som försetts med ett reliefmönster med fördjupningar 6. Hela reliefmönstret är täckt med ett tunt skikt 7 i vilket information kan lagras med hjälp av en laserstràle med tillräcklig effekt som faller in genom det transparenta skiktet mot skiktet 7. Där laserljuset träffar skiktat sker en förändring av skiktets optiska egenskaper, t ex genom att hal 8 bränns in. Läsning sker med samma laser men nu med så làg effekt att skiktets 7 egenskaper ej pâverkas. Det reflekterade ljuset detekteras och ger upphov till en med yttillstândet varie- rande signal som representerar den lagrade informationen. En övergång mellan en vid inskrivning belyst yta och en obelyst och vice versa kan tolkas som en binär etta medan oförändrat yttillstând markerar en nolla. _ , Spàret har lämpligen de dimensioner som är standard för digitala s k CD-skivor nämligen en spardelning på 1,6 ß m. Med en informationsbitarea av 1 - 2 /4 mmz kan man med de ca 150 spår som ryms pa en ringbredd av 0,3 mm fä in en datamângd av ungefär 2 Mbyte. 447 313 10 15 20 25 30 'i I I det i Fig l visade kortet är ett hal 3 anordnat i centrum av det ringformade omradet 2. Detta hal som exempelvis kan vara 15 mm i diameter passar till den roterande spindeln i ett drivorgan som för informationssparet förbi en fast läs- och/eller skrivstation sasom visas i Fig 4. Sparat 2 och halet 3 har i Fig 1 sitt centrum i kortets tyngdpunkt. Det är naturligtvis möjligt att placera spåret förskjutet fran detta läge som visas i Fig 2. l detta utföringsexempel är kortet ej försett med nagot centreríngshal 3 utan kortet avses samverka med ett roterande drivorgan försett med en hallare som haller fast kortet pa sadant sätt att det ringformade partiets 2 centrum sammanfaller med rotationscentrum.PREFERRED EMBODIMENT The data carrier 1 shown in Fig. 1 consists of a plastic card 1 suitably with the ISO standardized format approx. 54 x 86 mm. The card surface has a narrow annular information-bearing area 2. This area contains, for example, a spiral pair of the type described in the above-mentioned article in the Philips Technical Review but intended for writing. The file shown schematically in Fig. 3 in a sectioned perspective consists of a transparent base material 5 provided with a relief pattern with depressions 6. The entire relief pattern is covered with a thin layer 7 in which information can be stored by means of a laser beam with sufficient effect as falls in through the transparent layer towards the layer 7. Where the laser light hits the layer, a change in the optical properties of the layer takes place, for example by burning in hall 8. Reading takes place with the same laser but now with such a low power that the 7 properties of the layer are not affected. The reflected light is detected and gives rise to a signal varying with the surface condition which represents the stored information. A transition between an illuminated surface at enrollment and an unlit and vice versa can be interpreted as a binary one while an unchanged surface condition marks a zero. The track preferably has the dimensions that are standard for digital so-called CDs, namely a saving pitch of 1.6 ß m. With an information bit area of 1 - 2/4 mmz, you can with the approx. 150 tracks that fit on a ring width of 0 , 3 mm get a data amount of approximately 2 Mbytes. 447 313 10 15 20 25 30 'i II the card shown in Fig. 1 is a hall 3 arranged in the center of the annular area 2. This hall, which may for instance be 15 mm in diameter, fits the rotating spindle in a drive means which for the information pair past a fixed reading and / or writing station as shown in Fig. 4. The file 2 and the tail 3 have in Fig. 1 their center in the center of gravity of the card. It is of course possible to place the groove offset from this position as shown in Fig. 2. In this embodiment the card is not provided with a centering hall 3 but the card is intended to cooperate with a rotating drive means provided with a holder which holds the card in such a way that the annular the center of the party 2 coincides with the center of rotation.
I F ig 4 visas schematiskt hur en databärare enligt uppfinningen samverkar med en läs- och skrivenhet. Kortet 1 placeras pa en spindel 10 som passar i kortets hål 3. Spindeln drivs av en motor ll som styrs av en processorenhet 12. Ljuset för skrivning och avläsning alstras av en laser 13 med tillhörande optik och passerar en halvgenomskinlig spegel 14 eller alternativt ett polarisationsprisma och vidare genom en objektivenhet 15 som bryter ljusknippet till en ljusfläck som är nagot större än fördjupningarnas bredd. Objektivenheten innehåller anordningar dels för att ställa in fokuseringen dels för att förskjuts ljusstralen tvärs sparen. Sadana anordningar är i och för sig kända och beskrivs t ex i den citerade artikeln i Philips Technical Review. Objektivenhetens inställninga- anordningar styrs av servoenheten 21 för fokusering och 22 för inställning av stralen i radiell led i och för sparföljning fran första till sista spar.Fig. 4 schematically shows how a data carrier according to the invention interacts with a reading and writing unit. The card 1 is placed on a spindle 10 which fits in the holes of the card 3. The spindle is driven by a motor 11 which is controlled by a processor unit 12. The light for writing and reading is generated by a laser 13 with associated optics and passes a translucent mirror 14 or alternatively a polarizing prism and further through an objective unit 15 which refracts the light beam into a light spot which is slightly larger than the width of the depressions. The lens unit contains devices partly for setting the focus and partly for displacing the light beam across the tracks. Such devices are known per se and are described, for example, in the cited article in the Philips Technical Review. The lens unit setting devices are controlled by the servo unit 21 for focusing and 22 for setting the beam in radial direction and for tracking from first to last track.
Det fran kortytan reflekterade ljuset styrs av spegeln 14 till en detektorenhet 16 där ljusstralen pa känt sätt bringas att falla in mot ett antal fotosensorer, vars utgangssignaler efter viss signalbehandling ger tre signaler. Den första är en digital signal 18 representerande den lagrade informationen. Den andra är en spânningssignal 19 som används för att halla stralešw, kvar i spåret och som styr lägesservot 22. Den tredje är en fokuseringssignal som används till att ställa in laserstralens fokusering sa att ljusfläcken alltid faller pa kortets yta oberoende av eventuella skevheter och den styr fokuseringsservot 21.The light reflected from the short surface is controlled by the mirror 14 to a detector unit 16 where the light beam is made to fall in a known manner against a number of photosensors, the output signals of which after certain signal processing give three signals. The first is a digital signal 18 representing the stored information. The second is a voltage signal 19 which is used to hold the beam, remaining in the track and which controls the position servo 22. The third is a focusing signal which is used to set the focus of the laser beam so that the light spot always falls on the surface of the card regardless of any skew and it controls focusing servo 21.
Lässignalen matas till processorn 12 som efter ytterligare signalbehandling dels styr drivmotorn ll dels matar ut en datasignal pa utgången 23. Läs- och skrivenhetens funktion kan styras fran en ingang 24 pa processorn 12. Vid skrivning matas en skrívsignal in pa ingången 24. Varje gang en informationsbít 10 15 20 25 447 313 skall brännas in höjs effekten på lasern 13. Mellan informationsbitarna har lasern låg effekt och utnyttjas då för att hålla spårningen. Vid läsning har lasern 13 hela tiden låg effekt. 'r Uppfinningen är ej begränsad till den beskrivna utföringsformen utan den kan varieras på ett stort antal sätt inom ramen för uppfinningstanken. Data- registreringen behöver ej ske på det sätt som exemplifieras i F ig 3. I de flesta tillämpningar år det visserligen önskvärt att kortet skall kunna förses med data under användningen men det kan i vissa fall förses med fast information t ex på det sätt som används vid tillverkning av (ID-skivan.The read signal is fed to the processor 12 which, after further signal processing, partly controls the drive motor ll and partly outputs a data signal at the output 23. The function of the read and write unit can be controlled from an input 24 of the processor 12. When writing a write signal is input to the input 24. information bits 10 15 20 25 447 313 must be burned in, the power on the laser 13 is increased. Between the information bits, the laser has a low power and is then used to keep track. When reading, the laser 13 always has a low power. The invention is not limited to the described embodiment, but it can be varied in a large number of ways within the scope of the inventive idea. The data registration does not have to be done in the manner exemplified in Fig. 3. In most applications it is admittedly desirable that the card can be provided with data during use, but it can in some cases be provided with fixed information, for example in the manner used. in the manufacture of the (ID disc).
Dessutom är ett stort antal andra metoder kända som möjliggör skrivning av information på optisk väg med stor täthet. Några exempel på sådana kända metoder som kan tillämpas i samband med uppfinningen tillämpar ablation (t ex hålinbränning), formförândring (bubblor), fasförëndring (omkristallisation), strukturförändring (ytmönster), fotokromisom (färgförändring) och interferens (tvåvåglängdsmetoden). Ett lagringsmedium av detta slag kan tillverkas tomt på information eller delvis förprogrammerat. För att få enkel spårning förses sådana lagringsmedia med fasta spår i ett extra skikt eller som beskrivits ovan direkt i substratet. Över detta deponeras lagringsmediet som ett tunt skikt. lnskrivningen sker som beskrivits ovan med hjälp av en laser som kan vara samma som används vid läsningen men driven med en väsentligt högre effekt så att de eftersträvade förändringarna i skiktet uppstår.In addition, a large number of other methods are known which enable the writing of information on an optical path with high density. Some examples of such known methods that can be applied in connection with the invention apply ablation (eg hole burning), deformation (bubbles), phase change (recrystallization), structural change (surface pattern), photochromisome (color change) and interference (two-wavelength method). A storage medium of this kind can be manufactured empty of information or partially pre-programmed. For easy tracking, such storage media are provided with solid tracks in an additional layer or as described above directly in the substrate. Above this, the storage medium is deposited as a thin layer. The writing takes place as described above by means of a laser which can be the same as used in the reading but driven with a significantly higher power so that the desired changes in the layer occur.
Det är även möjligt att för ett dataregistreringsmedium enligt uppfinningen förse kortet med ett område av ett material som kan både skrivas och raderas på optisk väg. Exempel härpå är reversibla fasomvandlingar och magnetooptisk lagring.It is also possible for a data recording medium according to the invention to provide the card with an area of a material which can be both written and erased by optical means. Examples are reversible phase transformations and magneto-optical storage.
Det är också möjligt att lägga flera ringformade områden 2 koncentriskt. Dessa olika områden kan då innehålla information av skilda slag och läsas i läsenheter med flera radiellt förskjutna läshuvuden eller med separata läsare för varje spår.It is also possible to lay several annular areas 2 concentrically. These different areas can then contain information of different kinds and be read in reading units with several radially offset reading heads or with separate readers for each track.
