摘要： An optical information recording and reproducing apparatus comprising a first and a second laser diodes for generating recording light and reproducing light, respectively. A light emission condition of the second laser diode is always controlled to the constant or predetermined light intensity which is adequate for reproduction, by an APC circuit. The first laser diode is controlled by a light-intensity control circuit so as to be brought to the intensity of light emission lower than a level which forms a pit on an optical card, in a reproducing mode other than a period of time of a recording mode. Under a focus and tracking control due to the reproducing light, a value of a focus error and a value of a tracking error due to the recording light at a low level are detected and sampled/held as a focus offset and a tracking offset. During a period of time of the recoding mode, focus control and tracking control due to the reproducing light are performed so that these offsets are brought to zero.

A regenerating arrangement is provided for simultaneously scanning the plurality of tracks to which the optical head has irradiated the regeneration light spot, and then reading recorded information from the plurality of tracks. An error-correcting arrangement is provided which receives the recorded information read by the regenerating arrangement for performing error correction using the error-correcting codes for the plurality of tracks. An error-correction result memory arrangement is provided for storing results that indicate whether or not the error-correcting arrangement succeeded in error correction. A control arrangement is responsive to results stored in the error-correction result memory which indicate that error correction has not succeeded for the information regenerated from at least one track among the information regenerated from the plurality of simultaneously-scanned tracks. A driving device drives the regeneration light spot and the optical recording medium relatively to each other. The control arrangement controls the drive device so that the track for which the error correction has not succeeded will be included in a scanning range.

摘要： An optical recording/reproducing apparatus comprises a semiconductor laser, and a drive circuit for supplying a drive current to the semiconductor laser. A light beam from the semiconductor laser is converged on a recording medium through an objective lens. A photodiode for receiving the light beam is provided within the semiconductor laser. A monitor output from the photodiode is input to an APC circuit. The APC circuit includes a reference value generator and an error detector circuit. The error detector circuit detects a difference between the monitor output and a reference value, and outputs a control signal for controlling the drive circuit so as to keep the monitor output constant. The APC circuit is turned on/off by a controller. With the APC circuit turned on, the controller detects the temperature or temperature variance of the on the basis of the drive current monitor signal from the drive circuit and the pre-stored data of the semiconductor laser with respect to temperatures. With the APC circuit turned off, the semiconductor laser is supplied with a constant drive current from the drive circuit. The value of the drive current is set by the controller on the basis of the temperature detected just before the APC circuit is turned off and the pre-stored data on the characteristic of the semiconductor laser with respect to temperatures.

摘要： An apparatus for writing and reading information on and from an optical card by projecting a writing light beam and at least two reading light beams onto the optical card includes a first semiconductor laser for emitting a writing laser beam, a second semiconductor laser for emitting a reading laser beam, a diffraction grating for diffracting the reading laser beam into multiple reading laser beams, and an objective lens for projecting the writing laser beam and the reading laser beams onto the optical card. A reading laser beam spot is formed on the optical card at a middle point between two reading laser beam spots. Images of the reading laser beam spots are received by first and second light receiving elements, respectively. By processing output signals from the first and second light receiving elements, it is possible to verify the recorded condition of pits immediately after recording in regardless of a direction in which the optical card is moved. It is also possible to check the condition of the information track immediately before the writing. In this manner, the writing operation can be performed at a high speed in a suitable and reliable manner.

摘要： A CMD of XY address type is used as a photo detector. X and Y address signals output from the X and Y address generating circuit are applied to the CMD mechanically fixed to an optical head. Output from the CMD is binary-coded by a binary-coded circuit. A central position of a duration in which "H" continues in a mean-value circuit is stored by an X and Y address detection & memory circuit as a reference XY address. An address range is set in which reading is executed on the basis of the reference XY address. The XY address within this address range is assigned to produce an optical picture element signals within a corresponding light receiving region. A playback signal, a focus error signal and a tracking error signal are generated from the optical picture element signals.

摘要： In an optical card reproducing apparatus, the data of a front ID portion is read, and whether a track address can be identified is determined. If the track address cannot be identified, a flag is reset, and the data of a data portion is read. If the track address can be identified, whether the identified track address coincides with a target track address is determined. If they do not coincide, the operation is ended. If they coincide, the flag is set, and the data of the data portion is read. After the data read from the data portion is stored in a buffer memory, whether the flag is set is determined. If the flag is set, data in the buffer memory is output as the data of the target track. If the flag is reset, the data of a rear ID portion is read, and whether the track address is identified is determined. If the track address cannot be identified, the buffer memory is cleared, and the operation is ended. If the track address can be identified, whether the identified track address coincides with the target track address is determined. If they do not coincide, the buffer memory is cleared, and the operation is ended. If they coincide, data in the buffer memory is output as the data of the target track.
