Abstract

PURPOSE: In order to promote the write-in accuracy through reducing the time from the write-in frequency correction to write-in by means of installing the reference position at two points, through detecting the fluctuation between the rotary madia and the mark wirte-in frequency, thereby automatically correcting the write-in frequency.
