Abstract
The invention relates to a signal recording and reproducing method, and a storage medium processor. A buffer memory for temporarily storing a signal is provided. A boundary point is set in the buffer memory. An area for storing a signal to be recorded on a magneto-optical disc and an area for storing a signal reproduced from the disc are provided. A predetermined area for storing signals in an alternate sector is also provided. When reproducing operation is enabled, a ready command showing that recording and reproduction are enabled is supplied to a computer. Prefetch operation is started and the prefetched signal is stored in the buffer memory. When the computer supplies a write command before recording operation is enabled, a signal is stored in the buffer memory. When a signal is read, a desired signal can be promptly read from the buffer memory. Signal writing processing can be started before recording operation is enabled.
