Abstract
PURPOSE: To reduce errors that cannot be recovered and improve interchangeability of recording media by changing over the frequency response of a VCO in track units or for the the entire track simultaneously by using the error information when the error positions are to be reread.
CONSTITUTION: When an FF is set according to the error information having been detected with a magnetic recording control unit CONT and an instruction for rereading the error position arrives after this, then the signal passes through an AND circuit A and turns ON a switch S1. When reading of the error position was successful, the FF resets and the switch S1 goes OFF. By changing over the frequency response of the VCO in track units or for the entire track simultaneously by using this changeover means, the errors that cannot be recovered may be reduced and the interchangeability of the reording media may be enhanced.
