本発明は情報記録再生装置に係り、特に装置内部に複数

高速にて行1ようのに好適な情報記録再生装置に関する
。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an information recording/reproducing device, and particularly to an information recording/reproducing device that accommodates a plurality of disc-shaped recording media inside the device and records or reproduces information at high speed. The present invention relates to an information recording and reproducing device suitable for.
複数個の円板状記録媒体を内部に収容する情報記録再生
装置としては、例えば密閉形磁気ディスク装置のように
一本の回転軸上に複数個の前記円板状記録媒体を積層し
て固定し、回転運動の機構を簡単に実現したものがある
。この場合該円板状記録媒体に情報の記録および再生を

ティスフのように該検出装置が高価なものを使うような
時には、該記録媒体数が数10から数100に及ぶ場合
前記情報記録再生装置全体の価格が非常に高くなってし
まうという問題かあった。An information recording/reproducing device that accommodates a plurality of disc-shaped recording media therein includes a plurality of disc-shaped recording media stacked and fixed on one rotating shaft, such as a sealed magnetic disk device, for example. However, there are some that have a simple mechanism for rotational movement. In this case, each recording medium is provided with a dedicated detection device for recording and reproducing information on the disk-shaped recording medium. However, when the recording medium is bound or the detection device is expensive, such as an optical disk, the price of the entire information recording and reproducing device becomes very expensive when the number of recording media ranges from several tens to several hundreds. There was a problem with the price being high.
従って該情報記録再生装置を低価格で実現するためには
該検出装置の数を必要最少限に留める必要がある。その
ための一方法として該検出装置を移動可能な構造とし、
該検出装置が1個あたり複数個の前記円板状記録媒体に
対して記録および再生を行fg 5ように該情報記録再
生装置を構成することが容易に考えられる。Therefore, in order to realize the information recording and reproducing apparatus at a low cost, it is necessary to keep the number of detection devices to the minimum necessary. One method for this purpose is to make the detection device a movable structure,
It is easily conceivable that the information recording and reproducing apparatus is configured such that each of the detecting apparatuses records and reproduces data on and from a plurality of disc-shaped recording media.
しかしながら、該円板状記録媒体は同一回転軸上に積層

めには、該検出装置の各媒体への移動に加えてその方向
を180度変える必要があり、そのために該検出装置の
機構が一層複雑に71ってしまうという間覇があった。However, since the disc-shaped recording media are stacked and rotated on the same rotation axis, the upper recording area and the lower recording area of the disc-shaped recording medium are oriented in opposite directions. Therefore, in order to record and reproduce information signals in the upper recording area and the lower recording area using the same detection device, in addition to moving the detection device to each medium, it is necessary to change the direction of the detection device. It was necessary to make a 180-degree turn, which made the mechanism of the detection device even more complicated.
本発明の目的は上記の問題を解決し、最少の検出装置数
でしかも構造が簡単であるような情報記録再生装置を提
供することにある。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide an information recording/reproducing apparatus which requires a minimum number of detection devices and has a simple structure.

出装置をそれぞれ別個に設け、各々の役割を分担させる
ことにより。In order to achieve the above object, the present invention includes a detection device for recording and reproducing information on the upper recording area of a disc-shaped recording medium, and a detection device for recording and reproducing information on the lower recording area of the disc-shaped recording medium. By establishing them separately and having them share their roles.
少ない検出装置数でかつ検出装置が反転機構のいらない
簡単な構成となるようにしたものである。The number of detection devices is small and the detection device has a simple configuration that does not require a reversing mechanism.
以下、本発明の一実施例について図面により説明する。 An embodiment of the present invention will be described below with reference to the drawings.

は効果が大きい。The figure shows an example of the present invention applied to an optical video disc. Reference numeral 1 denotes a disk, which is stacked and fixed on a rotating shaft 2 and rotates as a unit. 3 and 4 are both optical heads, the upper head 6 performs recording and reproduction on the upper recording area of the disc 1, and the lower head 4 performs recording and reproduction on the lower recording area of the disc 1. Let's do it. The upper head 6 and the lower head 4 are attached to dedicated positioners 7 and 8 via arms 5 and 6, respectively, and can each move independently. Positioners 7 and 8 are movable vertically and horizontally in the figure, and by moving vertically they select one of the stacked disks 1, and by moving horizontally they select one of the recording tracks on disk 1. Select a book. According to the configuration of this embodiment, since the recording area on the disk 1 handled by the upper head 6 and the lower head 4 is limited to one direction, a mechanism for rotating the heads is unnecessary and the configuration is It will be easy. Further, since the upper head 3 and the lower head 4 can move independently, for example, while the upper head 3 is recording or reproducing information, the lower head 4 is used to determine the next place to record or reproduce information. By configuring the recording and playback software to search, it is possible to shorten the search time. This is especially effective when finding desired information while reproducing information.
上記の例では、上側下側各1個のヘッドを用いた場合を
示したが、ディスク枚数が非常に多い時には図に示した

ある。またディスク枚数が多い時には図のように回転軸
が1本の場合だけでなく、数本の回転軸にディスクを分
配した構成においても本発明が実施できることは言うま
でもない。The above example shows the case where one head is used for each of the upper and lower sides, but if the number of disks is very large, multiple heads for the upper and lower sides may be installed as shown in the figure. It is also possible to shorten the search time by allocating a disk for recording and reproduction to each head. It goes without saying that when the number of disks is large, the present invention can be implemented not only in the case of one rotating shaft as shown in the figure, but also in a configuration in which the disks are distributed over several rotating shafts.
また説明の都合上円板状記録媒体が光学式ディスクの場
合に限って説明を行なったが、円板状記録媒体であって
両側に記録領域を持つようなものであれば、光学式に限
らず静電容量式、磁気式1機械式の記録媒体についても
本発明は応用が可能である。Also, for the sake of explanation, the explanation was given only when the disc-shaped recording medium is an optical disc, but if it is a disc-shaped recording medium with recording areas on both sides, it is limited to the optical disc. The present invention is also applicable to capacitive, magnetic, and mechanical recording media.
以上説明したように本発明によれば、検出装置の向きを

つことができるので、検出装置数の増加による情報記録
再生装置全体の価格の上昇を押えることができる。As explained above, according to the present invention, a rotation mechanism for changing the direction of the detection device is not required, so that the device can be simplified. Furthermore, since the number of detection devices can be kept to the minimum necessary limit, it is possible to suppress an increase in the price of the entire information recording and reproducing apparatus due to an increase in the number of detection devices.
