Title: Optical information recording and reproducing device
Inventor: SAITO AKITO
IPC: G11B19/04
Filed: 1990-02-09
Abstract: PURPOSE:To prevent a reproducing error and write damage by detecting a relative moving speed between a medium and an optical head and inhibiting recording and/or reproducing of information when the relative moving speed does not maintain a prescribed speed. CONSTITUTION:A controller 10 is previously set with passing time when a shuttle 6 passed an ID part at a target speed as a target value. Then, a discrepancy between an average speed of the shuttle 6 at the ID part and the target speed is detected by the controller 10 from a speed detecting signal and the target value. When the speed detecting signal is smaller than the target value, the average speed is faster than the average speed, and on the contrary, when the speed detecting signal is larger than the target value, the average speed is slower than the target speed. The recording is not performed in such cases that because of write damage when the average speed is faster than the target speed by >=3%, and as speed abnormality when the speed is faster by >=2%. Then, when the average speed is slower than the target speed by >=2%, a margin at the time of reproducing is decreased, so that the recording is not performed due to speed abnormality in the same way as the faster case.

Title: Demodulation circuit for high frequency magnetic field
Inventor: HATAYA MITSUTERU
IPC: A61N2/00
Filed: 1992-02-14
Abstract: PURPOSE:To detect a duty of a high frequency magnetic field at a low current consumption by the demodulation circuit for a high frequency magnetic field. CONSTITUTION:A reception signal of a high frequency magnetic field is amplified by a low frequency amplifier circuit 1 to detect the presence of a reception signal and amplified by a high frequency amplifier circuit 5 to detect a duty of a reception signal. Moreover, only when the reception signal of the high frequency magnetic field is detected, the high frequency amplifier circuit 5 is activated. In comparison with a conventional embodiment amplifying the reception signal by the low frequency amplifier circuit 1, the duty of the reception signal of the high frequency magnetic field is accurately detected. Since the high frequency amplifier circuit 5 is activated only when the reception signal of the high frequency magnetic field is detected, the increase in the current consumption by the high frequency amplifier circuit 5 is prevented and the duty is detected at a low current consumption.

Consequently, an arrangement correcting means 7 corrects the arrangement of the blocks to the inputted position. A clock system net logic replacing means 8 replaces the logic of the clock net after the arrangement of the blocks is corrected.
