摘要： A circuit for and a method of the operation of moving an optical pickup to a target track set on an optical disk, that is, the seek operation. The seek circuit determines the address of the current track from the address information in reproduced signals from the optical disk, generates a reference value which changes with time during the period the pickup move to the address of the target track from the address of the current track, and drives means for causing movement of the optical pickup in the radial direction of the optical disk in accordance with the difference between the address of the current track and the reference value. In this manner, according to the present invention, a high-speed seek operation can be made without using a speed sensor.

摘要： According to the present invention, a detection signal Sk1 whose signal level rises or falls in a period longer by a predetermined period of 0.5T than the period T of a clock signal SCk is generated on the basis of a reproduction signal SRF obtained from an optical disc on the recording tracks of which recording patterns are recorded with a predetermined period, and this detection signal Sk1 is acquired at the timing of the clock signal described above to obtain a plurality of recording pattern detection signals Sp1 by sequentially representing the signal level of the detection signal SCK during a predetermined period by the period T of the clock signal described above. The recording pattern is detected except for part of the plurality of recording pattern detection signals Sp1.

摘要： This invention relates to a photomagnetic recording method for writing data into a photomagnetic medium by using a magnetic head whose magnetic field is modulated by a recording signal and an optical pickup. In accordance with the present invention, a first data pit group is first recorded on the photomagnetic recording medium with gaps greater than a predetermined data pit recording gap and then each data pit of a second data pit group is recorded between the adjacent data pits of the first data pit group. A photomagnetic recording apparatus according to the present invention can cope, by interleaving write method, with both the factors of frequency characteristics of the magnetic head and the thermal interference of adjacent pits that limit high density recording or high speed access, and can accomplish both high density recording and high speed access.

摘要： An optical disc which serves both as a program disc and as a data disc by utilizing the fact that an optically recording/reproducing disc (1) has a very large capacity. Namely, onto a predetermined region (5) of the disc non-rewritably recorded in advance are a software program necessary for processing the data recorded in the optical disc (1) or the basic data necessary for executing the program, as well as an erasing program for executing the erasing operation for the recording region. Even in case the software programe and the basic data for executing the program are copied without authorization, the copy disc is prevented from being used.

摘要： An objective lens (3) of an optical pick-up head (10) is moved in a direction of the optical axis, and a signal level of the output detected by the optical pick-up head (10) before and after a focussed state is compared with predetermined reference levels (Vref1) and (Vref2) by level comparators (32) and (33), in order to discriminate the reproduction-only disc from the recording disc by utilizing a difference in the reflection factor on the recording surface of the optical disc (20). Operation of the optical disc recording/reproducing apparatus is automatically switched over depending upon the kind of the optical disc.

摘要： Apparatus and method of recording and reproducing data using a disk (1) to record data of music play. Data related to music numbers and times of start for each of pieces of music are recorded onto a TOC portion (6) of the disk (1), and the operation is controlled on these data. Therefore, wasteful reproducing operation is avoided either even when there exists non-recorded portion between pieces of music or even when a music shorter than the initial music is recorded overlapped thereon, enabling the music to be favorably reproduced. In carrying out the (sound) recording operation, furthermore, the non-recorded portions can quickly be found.
