The gap between the main beam and the sub-beam is made a value of an integral multiple of a channel bit interval plus the half of the former. During a writing, the period when a second level erase power is raised to a first level write power is made approximately the half of a channel period. Moreover, a data reproducing is performed by the sub-beam in synchronism with a clock which has an opposite phase to a main clock. Thus, a simultaneous verification is exactly performed using a single light source without gain adjustment.
