Abstract

PURPOSE:To discriminate a back tracking in the state of the period and phase of a reproduction control signal being stable by providing the discriminating pulse generator generating the timing signal actuating a back tracking reproduction discriminator only for a fixed period after the fixed time from the start of reproduction. CONSTITUTION:The titled device has the discriminating pulse generator 4 generating the pulse stipulating the operation period of the back tracking reproduction and discrimination. Namely, a record control signal [REC CTL(IN)] is inputted to the 1st input 11 of a duty converter 1, a head switching signal (HSW) to the 2nd input 12 and 1/2 HSW to the 3rd input 13 respectively and the output is connected to the control signal (CTL) head. A reproduction control signal (PB CTL) is inputted to the 1st input 21 of a back tracking discriminator 2, the HSW to the 2nd input 22, the 1/2 HSW to the 3rd input 23 and the discriminating pulse to the 4th input 25, and an output 24 is inputted to the 1st input 31 of an accelerating pulse generator 3. The back tracking reproduction can thus be correctly discriminated when the period and phase of the reproduction control signal is stabilized after starting the reproduction.
