摘要： The recording and reproducing apparatus comprises an Small Computer System Interface (SCSI) controller, an optical disc device, a magnetic disc device, a disc controller which controls the optical disc device and the magnetic disc device, connectors which connects directly the optical disc device and the magnetic disc device, and a selector which selects one of the optical disc device and the magnetic disc device. A Copy or Verify command is carried out within the apparatus without an SCSI bus, and data are transferred through the connector. Therefore occupation of the SCSI bus and overhead of the SCSI protocol are eliminated, and the apparatus is miniaturized by common use of the SCSI controller and the disc controller.

摘要： A record carrier having a disc-shaped substrate and a recording layer for optically writing information therein is disclosed which includes a guide groove extended in the rotational direction of the record carrier so that a plurality of revolutions of the guide groove are spaced apart from each other in radial directions of the record carrier, and a pit pattern provided between adjacent guide grooves, at positions arranged at intervals in the above rotational direction, for detecting the deviation of a light spot from the center line between adjacent guide grooves. The recording/reproducing operation for this record carrier is performed in such a manner that the first tracking error signal is detected from diffracted light from the guide groove, the second tracking error signal is detected from the pit pattern, and information is recorded in and reproduced from a land formed between adjacent guide grooves in a state that a tracking operation is performed using the first and second tracking error signals. The second tracking error signal detected from the pit pattern is not affected by the tilting of the record carrier and the movement of the light spot. When a tracking signal obtained by adding the first and second tracking error signals to each other, is used in a closed-loop tracking system, a stable tracking operation can be performed. The polarity of the pit pattern is reversed on every track, and hence a polarity pit having a depth of .lambda./4 (where .lambda. indicates the wavelength of a reproducing light beam) is provided in the record carrier, to reverse the polarity of the second tracking signal on every track on the basis of a signal from the polarity pit.

摘要： A low-laser-noise semiconductor driver device is provided for use in an optical information processing device which is recordable or erasable and which oscillates a semiconductor laser with a high output when it is recorded or erased. A semiconductor is generally oscillated with a rated maximum output during a recording and erasing operation. Therefore, when high frequency superposition is made in such a high output oscillation state, an oscillation output exceeds the rated output, which badly influences the life of the laser. To obviate this drawback, the high frequency superposition is stopped at the mode of recording or erasing in which the high output oscillation is made by a switching circuit which is controlled by a mode control signal. This reduces the laser noise at the mode of reproducing and also lengthens the life of the semiconductor laser. The semiconductor laser driver device can be also used as a light source of the optical information processing device which can record and/or erase information.
摘要翻译：提供了一种用于可记录或可擦除的光学信息处理装置的低激光噪声半导体驱动器装置，并且当记录或擦除时具有高输出的半导体激光器振荡。在记录和擦除操作期间，半导体通常以额定最大输出振荡。因此，当在这样的高输出振荡状态下进行高频叠加时，振荡输出超过额定输出，这严重影响激光器的寿命。为了避免这种缺点，在通过由模式控制信号控制的开关电路进行高输出振荡的记录或擦除模式下，高频叠加停止。这就降低了在再现模式下的激光噪声，并延长了半导体激光器的寿命。半导体激光驱动器装置也可以用作可以记录和/或擦除信息的光学信息处理装置的光源。
