Abstract

PURPOSE:To shorten a copying processing time, by performing the readout of an optical disk on a source side and the write of the optical disk on a destination side in parallel. CONSTITUTION:By starting up a copying processing, data in the optical disk 2 is transferred to a buffer memory 5 by an optical disk drive 1 based on the control of a controller 12 via a RAM11 according to an instruction from a microprocessor 9. All of the data, after being accumulated in the memory 5, are transferred to the destination side via a data transfer port 13. The microprocessor 16 makes a DMA controller 19 transfer reception data from a transfer port 20 to a buffer memory 6. After reception is completed, information to perform the write control of the data in the memory 6 on the optical disk 4 is set on a RAM18. Processors 9 and 16 perform the readout of the data on the source side and the write on the destination side in parallel by respective control program.
