Description

(54) УСТРОЙСТВО ДЛЯ ФОТООПТИЧЕСКОГО ВОСПРОИЗВЕДЕНИЯ ИНФОРМАЦИИ С ВРАЩАЮЩЕГОСЯ ДИСКОВОГО НОСИТЕЛЯ ЗАПИСИ(54) DEVICE FOR PHOTOOPTICAL REPRODUCTION OF INFORMATION FROM ROTATING DISK MEDIA RECORDING

Изобретение относитс к области приборостроени , а именно к оптической записи и воспроизведени .The invention relates to the field of instrumentation, namely to optical recording and reproduction.

Известно устройство дл фотооптического воспроизведени информации в котором воспроизведение осуществл етс посредством электронно-лучевой трубки с бегущим световым лучом. Сигнал отиибки, характеризующий степень и направление отклонени траектории развертки бегущего луча от каждой дорожки, используетс дл изменени скорости движени носител .A device for photo-optical information reproduction is known in which reproduction is carried out by means of a cathode ray tube with a running light beam. An end signal, characterizing the degree and direction of deviation of the traveling beam sweep path from each track, is used to change the speed of movement of the carrier.

Однако така система при больших плотност х записи сложна, так как требуютс прецизионные механические приводы 1.However, such a system with large recording densities is complicated, as precision mechanical drives are required.

Наиболее близким к изобретению по технической сущности вл етс устройство фотооптического воспроизведени информации с вращающегос дискового носител записи, содержащее источник лучистой энергии, объектив с механизмом его перемещени по радиусу дискового носител , зеркало, диафрагму и фотоприемник, соединенный с входом усилител 2. Слежение за информационной дорожкой осуществл етс подачей корректирующего сигналаThe closest to the invention in technical essence is a device for photooptical reproduction of information from a rotating disk recording medium containing a source of radiant energy, a lens with a mechanism for its movement along the radius of the disk carrier, a mirror, a diaphragm and a photodetector connected to the input of the amplifier 2. Tracking the information track carried out by applying a correction signal

с усилител на привод, который перемещает зеркало.with an amplifier on a drive that moves a mirror.

Недостатки известного устройства- низка точность слежени из-за наличи инерционной механической системы и невысока скорость воспроизведени информации.The disadvantages of the known device are low tracking accuracy due to the presence of an inertial mechanical system and low speed of information reproduction.

Целью изобретени вл етс повышение скорости воспроизведени ин0 формации и уменьшение скорости движени носител .The aim of the invention is to increase the speed of reproduction of information and reduce the speed of movement of the carrier.

Это достигаетс тем, что предлагаемое устройство снабжено электронно-оптическим преобразователем с This is achieved by the fact that the proposed device is equipped with an electron-optical converter with

5 двум парами отклон ющих пластин и генератором пилообразного напр жени , выход которого подключен к одной из пар пластин, при этом друга пара пластин св зана с выходом уси0 лител и управл емым входом указанного генератора.5 with two pairs of deflecting plates and a sawtooth generator, the output of which is connected to one of the pairs of plates, while the other pair of plates is connected to the output of the amplifier and the controllable input of the specified generator.

На чертеже изображена структурна схема описываемого устройства.The drawing shows a block diagram of the described device.

Устройство содержит дисковый но5 ситель информации 1, закрепленный на прозрачном диске 2, источник 3 лучистой энергии, объектив 4 и механизм 5 его перемещени , зеркало 6, элек тронно-оптический преобра зоваThe device contains a disk information carrier 1, mounted on a transparent disk 2, a source of radiant energy 3, a lens 4 and its movement mechanism 5, a mirror 6, an electron-optical conversion.
