摘要： A beam-spot control unit is arranged such that a light beam is irradiated onto an optical recording medium having a plurality of tracks, through an objective lens, to detect reflecting light of beam spots formed on the tracks by three or more photo detecting elements which are arranged in a direction corresponding to a track transverse direction. From a tracking error signal which is generated by a difference signal of pairs of photo detecting elements which are selected by a selecting switch from these photo detecting elements, a control signal is generated which positions the beam spots to a plurality of recording lines within a single track. A tracking control mechanism is utilized to enable positioning of the beam spots to a plurality of recording lines within the single track to be performed.

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.

摘要： According to the optical information recording/reproducing device of the present invention, upon recording of information, when a pit image on an optical detector which is formed by a recording optical beam spot at an information recording time arrives at a position of a O-order diffraction light spot image, while an optical card is moving in the forward direction, a light receiving element for signal reproducing senses a change in light amount. A verify signal is obtained immediately after recording based on the light amount change to perform a verify operation. Further, when a pit image on the optical detector formed by the recording optical spot arrives at a position of the image of the primary diffraction optical spot while a moving direction of the optical card is reversed and the optical card moves in the reverse direction to perform recording, a signal reproducing light receiving element senses a change in light amount. A verify signal is obtained immediately after recording based on the light amount change to perform a verify operation. Since irradiation is made in which the space between the recording optical spot and the O-order diffraction light spot is made equal to the space between the recording optical spot and the primary diffraction light spot b, an optical detector can receive the verify signal at the same timing even if the optical card moves in the forward or reverse direction.

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.

摘要： An optical information recording/regenerating apparatus includes an optical head for irradiating a regeneration light spot to a plurality of tracks on an optical recording medium simultaneously via an objective optical system. 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.
