摘要： In a magnetic recording medium wherein a light beam is projected onto a data track (14) between optical grooves (12) for tracking a magnetic head and the magnetic head is tracked according to the reflection beam produced by the projection, the tracking servo is properly performed by reducing the fluctuation of the reflection factor in the frequency region from 100 Hz to 2 kHz under 4 dB, and by presetting the thickness of a magnetic layer (10a) on the data track (14) or the depth of the grooves (23) within a specified range. The reliability of the magnetic recording medium is improved.
