Filed: 1990-08-10
Abstract: PURPOSE:To exactly execute the error detection without complicating the circuit configuration by detecting an error by using a write clock synchronized with a reproducing signal, in the case a detecting signal of a zero crossing point does not exist. CONSTITUTION:The device is provided with a zero crossing detecting circuit 304 for detecting a zero crossing point from a reproducing from a reproducing signal from a magnetic recording medium in which write data is recorded by synchronizing with a write clock WCLK, a voltage comparing circuit for compar ing the reproducing signal with a reference voltage, and an error detecting circuit 302 for detecting an error of the reproducing signal, based on output signals of the zero crossing detecting circuit and the voltage comparing circuit. In such a state, when the zero crossing point is not detected from the reproduc ing signal by the zero crossing detecting circuit, in the error detecting circuit, the write clock WCLK is used instead of a detecting signal of the zero crossing point. That is the write clock is a stable clock, and also, becomes a signal synchronized with the reproducing signal. In such a way, the error detection can be executed exactly without complicating the circuit configuration.

Abstract: PURPOSE:To reduce the occurrence of hunting and to prevent the quick change of a set value due to external noise by providing a blind sector so that the set value is not changed when a deviation voltage is lower than a prescribed value. CONSTITUTION:A pair of reverse connected diodes d1 and d2 are connected to the output of an amplifier 10 which amplifies the deviation voltage by prescribed times, and a voltage/frequency converter 12 is connected to outputs of these diodes.

If the deviation voltage exceeds the forward voltage of diodes, the voltage of the excess is inputted to the converter 12 and a pulse having a frequency corresponding to the inputted voltage value is generated, and this pulse is counted up or down by a counter 2.
