IPC: G11B20/14
Filed: 1991-11-14
Abstract: PURPOSE:To obtain a stable synchronous signal which is not affected by the peak shift of a regenerative signal by controlling an output phase of such a VFO that has the amplitude error of zero set between the actual sample value and the sample value obtained at the original timing position. CONSTITUTION:An error detecting circuit 9 obtains an amplitude error between the actual sample value and the sample value obtained at the original timing position. When a synchronizing clock is produced, the regenerative signal read out of a magnetic head is amplified by a read amplifier 1. This output signal is turned into a differential waveform by a differential circuit 5 and then turned into a digital signal by an A/D converter 6. Meanwhile a loop filter 7 produces such a signal that advances (INC) or delays (DEC) the output phase of a VFO 8 from the differential output and the error output obtained from the circuit 9. So that the amplitude error is equal to zero. Then a synchronous signal is outputted from the VFO 8 and serves as the reference clock of a data identification circuit 4, etc.
