Title: Optical disk recorder
Inventor: OSAKABE KATSUICHI
IPC: G11B7/00
Filed: 1987-06-01
Abstract: PURPOSE:To reduce jitter in a reproducing signal, to improve an S/N, and to reduce an error by decreasing the projecting time of a laser beam in a case where a just before blank length forms a short pit. CONSTITUTION:An optical head 13 performs recording or reproduction by projecting a recording or reproducing laser beam generated from a laser generation circuit 14 on the plane of a disk 11 being rotated at constant linear velocity. In such a case, a laser beam control means decreases the projecting time of the laser beam in the case where the just before blank length forms the short pit. Therefore, tendency to form the it length in a larger size can be negated, and the pit length almost equal to a regulated value can be formed. In such a way, it is possible to obtain the reproducing signal with a few quantity of the jitter and the error and with a superior S/N.

Abstract: PURPOSE:To attain a signal process with an optimum amplification factor and to widely read the recording state of codes by fixing the amplification factor in a single period when a code is scanned and detected and changing the amplification factor in a scanning period. CONSTITUTION:The laser beams irradiating a bar code surface 20 are condenced to a photodetecting element 16 as the reflected beams and supplied to a preamplifier 8 which compares the photodetecting signal obtained based on the reflected beam quantity with the reference voltage Vref supplied from an amplifier 9 and amplifies the signal. Then an analog signal es which is preliminarily amplified is supplied to an amplifier circuit 9 from a deflection control part 4. The circuit 9 updates the amplification factor and the reference voltage Vref for amplifying action based on a scan period signal ST which is outputted in response to the rotary action of a galvanoscanner 19. Then a fixed amplification factor is kept in a period of the reading operation and then varies and amplifies at shift to the next period. A decoding operation is carried out with an amplification factor that can obtain a readable rectangular wave signal within plural scanning operations. Thus it is possible to cope with a wide medium recording state.
