Abstract

PURPOSE: To make rewrite of cue signals possible without influence upon recorded control signals by using a PLL.
CONSTITUTION: Reproduced signal A from control track 3 is applied to positive- polarity amplifier 11 to extract control signal B, and signal B is applied to PLL 18, and output pulse C of the PLL is used for rotation speed control of the rotary head/ capstan, and simultaneously, pulse C is supplied to cue signal generation circuit 16 and gate pulse generation circuit 17. Circuit 16 generates a positive pulse of time width T2 instructed with pulse C as the start point during two sections where cue signal update recording command signal H is received, and generates negative-pulse cue signal D until the next pulse C comes. Then, cue signal F is generated in 15 by signal D and gate pulse E and is recorded as a new signal by head 6. As the result, the cue signal interval is changed from T1 to T2.
