PURPOSE:To consecutively reproduce plural events at random without joints by providing a magneto-optical head use for erasure/reproduction and a magneto-optical head used for recording/reproduction so as to specify the arrangement thereby attaining the overwrite of a real time signal. CONSTITUTION:When a 1st magneto-optical head 3a is located at the head of a sector address SA of an optional sector S, a 2nd magneto-optical head 3b is placed at the head of a front gap SG1' in gaps SG1', SG2' before and after the sector address SA' of another sector S'. When the 2nd magneto-optical head 3b is placed at the head of the sector address SA' conversely, the 1st magneto-optical head 3a is placed at the head of the rear gap SG2 in the gaps SG1, SG2 before and after the sector address SA' of the other sector S. Thus, the disk having preceding recording has a new signal in nearly real time immediately and events are reproduced consecutively without timewise section at random one after another at the reproduction. |
