Abstract:
1. An optical disk recording system comprising: an optical disk; an optical disk drive unit that includes a buffer storage portion that temporarily stores data transferable from a host device, and a rotating portion that holds and rotates the optical disk and outputs an angle position signal, the optical disk drive unit performing a recording operation to record on the optical disk a visible image corresponding to the data; and the host device that is provided for transferring the data to the optical disk drive unit, wherein the optical disk drive unit interrupts the recording operation when an error of data emptiness in the buffer storage portion occurs in the course of recording during a predetermined revolution of the optical disk, the host device resumes transfer of data after discarding data corresponding to a section between a position where the error occurs and a reference angle position on the optical disk, and the optical disk drive unit resumes receipt of data, to resume the recording operation from the reference angle position.
