US Patent 7652959 Optical disk device

An optical disk device includes a BE control means which issues a request for recording of data upon an optical disk. Furthermore, this optical disk device includes an FE processing means which, upon receipt of the recording request from the BE control means, irradiates laser light from a pickup head onto the optical disk, and records data stored in a buffer RAM upon the optical disk. If an error has occurred during the recording of the data upon the optical disk by the FE processing means, then the BE control means first acquires, from the FE processing means, error information including an error occurrence address. And the BE control means performs control to execute recovery processing, according to this error information.
