METHOD AND APPARATUS FOR RECORDING DATA IN OPTICAL MAGNETIC RECORDING MEDIUM

摘要

PURPOSE: A method and an apparatus for recording data in an optical magnetic recording medium are provided to minimize an irregularity of data by generating a synchronizing error signal and synchronizing a laser driving signal to a magnetic head driving signal. CONSTITUTION: A synchronization detection unit(54) generates a synchronizing error signal. A record stabilizing unit(52) sets a synchronization between a laser driving signal and a magnetic head driving signal. The synchronization detection unit(54) controls a magnetic head driving unit(56) and a laser diode driving unit(58) and detects an asynchronous point between the magnetic head driving signal and the laser driving signal through the synchronization error signal. The magnetic head driving unit(56) controls current supplying to a magnetic head(8) under the control of the synchronization detection unit(54). The laser diode driving unit(58) controls current supplying to a laser diode(4) by a control of the synchronization detection unit(54).
