ABSTRACT:
A disk apparatus for reproducing pulse width modulation (PWM) data from a disk is disclosed. A first sync pattern detector compares data DTLE with a first sync pattern. A second sync pattern detector compares data DTTE with a second sync pattern. A first signal generator stops the detecting operation of the first detector when the first detector has detected the first sync pattern from the data DTLE. A second signal generator stops the detecting operation of the second detector when the second detector has detected the second sync pattern from the data DTTE. A first time check circuit restarts the detecting operation of the first detector when the first sync pattern has been detected first and the second sync pattern is not detected within a predetermined period of time. A second time check circuit restarts the detecting operation of the second detector when the second sync pattern has been detected first and the first sync pattern is not detected within a predetermined period of time.
