ABSTRACT:
An object of this invention is to provide an optical disc controller and an optical disc drive system which reduce the proceeding time for supplementing data that is deficient at the time of writing to the optical disc. The present invention relates to an optical disc controller and a optical disc drive system. An optical disc controller includes an interface circuit, a buffer, a memory manager, an ECC circuit, a modulation circuit, and an operation processor. The memory manager has a control register part, a copy transfer controller, and a buffer controller. The control register part further includes a copy sector number setting register for taking out and holding information of plural sector numbers of deficient data from a control signal of the operation processor. The copy transfer controller successively conducts copy transfer process for plural sector numbers based on the sector number information.
