METHOD FOR RECORDING POSITION SIGNAL AND MAGNETIC RECORDING DEVICE USING METHOD

PROBLEM TO BE SOLVED: To solve the problem that the width of a burst pattern is narrowed as compared with prescribed width due to the influence of erasing width by trimming the burst pattern width by DC erasing. SOLUTION: The burst pattern width is trimmed by writing a high frequency signal whose er...

Summary:PROBLEM TO BE SOLVED: To solve the problem that the width of a burst pattern is narrowed as compared with prescribed width due to the influence of erasing width by trimming the burst pattern width by DC erasing. SOLUTION: The burst pattern width is trimmed by writing a high frequency signal whose erasing width is narrower. The high frequency signal pattern is erased by writing a signal having a reversed phase and the same frequency. COPYRIGHT: (C)2005,JPO&NCIPI
