Title: Disk driver
Inventor: TSUYUKUCHI YUUJI
IPC: G11B19/20
Filed: 1983-07-29
Abstract: PURPOSE:To reduce the power consumption amount and to detect accurately an index by turning on the light emitting elements consecutively for a period between the generation of a motor ON signal and the generation of a preparation end signal, then turning on intermittently those elements in response to the pass of the index. CONSTITUTION:When a motor ON signal is produced at a time point t1, the output of NOT circuit 34 is set at a low level. At the same time, the output of NOR gate 27 is also set at a low level. Thus light emitting diodes L1-L5 are turned on consecutively regardless of the output of a counter 29. Hereafter, the elements L1-L5 are turned on earlier by 20msec than a time point when an index hole 20 has passed through a photodetector. Therefore, the diodes are turned on while the hole 20 is passing, and an index can be detected. Furthermore the power consumption is greatly reduced and the diodes L1-L5 can be easily controlled since these diodes are connected in series.
