Title:
TEMPORARY STOP DEVICE OF DISK REPRODUCER
Document Type and Number:
Japanese Patent JPS59107457
Kind Code:
A
Abstract:
PURPOSE:To continue reproduction information when the reproduction is started again after a temporary stop by dividing 75 frames larger than the frame number converted into the maximum time required for a revolution of a disk and using the number of divided frames to the comparison data. CONSTITUTION:The time required for a revolution of a disk is converted and equivalent to 8.41-22.8 frames, and the position index signal is detected by a detecting circuit 5 among those signals read out by a pickup means 1 and then supplied to a coincidence circuit 9 in the frame number equivalent to 75 frames per second. Then 25, 50, 00, etc. which indicate the numbers of frames obtained by dividing 75 frames into plural numbers are compared and decided by the circuit 9 as the coincidence data. Therefore a track jump pulse generating circuit 10 is driven so that the read-out point of the means 1 is positioned at a place near the read-out point set when the temporary stop is started.
