Abstract

PURPOSE: To make it possible to display abnormality of a medium rapidly by detecting the existence of the abnormality by automatically seeking for track "0" when the medium is loaded in a unit and then by displaying the detection result.
CONSTITUTION: When an operator loads a medium and the medium reaches its steady rotation, mechanism part 3 outputs operation-enabling-state rise signal 11, by which head control circuit 1 sends track-"0" seek signal 12 to head driving circuit 2. Then, circuit 2 supplies driving signal 13 for a head to mechanism part 3, which when the head reaches track "0", starts read operation to send information read signal 14 to reading circuit 5. Circuit 5 performs waveform shaping, data array, etc., to output signal 15 to abnormality detecting circuit 4, which supervises signal 15 to detect the CRC error of data, the CRC error of the ID part, etc., and then supplies abnormality signal 16 to display part 6 when the abnormality is detected.
