Abstract
PURPOSE: To simplify the operation, by performing the leading-in of the head to the track address preset, through the use of the information such as track address recorded in advance in the track of a disc.
CONSTITUTION: The information such as track address at the 20th H is picked up with the gate flag signal from the composite video signal A at the gate 5 and fed to the shift register group 10 and the clock pulse generating circuit 5' as the pick up signal D. The clock pulse B from the circuit 5' is produced with a little delay from the signal D, the signal D is read in to the circuit 10 at the leading of the pulse B, it is sequentially shifte, and the 23 bits of the signal D are all stored. Further, the content of the circuit 10 is parallelly outputted by 8-bit and it is fed to the microcomputer via the AND gates 14 to 16 and the OR gate 17. Further, the pick- up is moved to the track address preset to perform movement control further.
