Abstract
An optical disk apparatus records new information related to the ROM information into RAM at a position linked with the ROM information of an optical information storage medium while continuously regenerating the ROM information of the optical information storage medium. At least the ROM signals are read at n (n>2) times of the information regeneration velocity V, which is a reference, and stored in a buffer memory for reading, then the stored information is output at a velocity of the information regeneration velocity V. And while the stored information is being output from the buffer memory for reading, the input information is stored in the buffer memory for writing, then the optical head is accessed an address position that is managed so that the time relationship of the output information and the input information link for recording.
