Patent ID: 7023781

Claim:
An optical disk apparatus for recording and reproducing information to an optical disk, said optical disk apparatus comprising: a data storing part temporarily storing data externally transferred to be written on said optical disk; a data processing part for conducting a predetermined data process for said data stored in said data storing part; an encoding part modulating and outputting said data processed by said data processing part; a write-in controlling part conducting an operation control of said data processing part and said encoding part, and conducting a storing control for storing said data to be written to said storing part; and a write-in operation instruction part detecting a state of interrupting supplying said data to be written to said data storing part, and sending an operation instruction to said write-in controlling part in accordance with a detection result; wherein when said write-in controlling part interrupts writing of data to the optical disk, said write-in controlling part sets said data processing part and said encoding part in a waiting state after an access to said data storing part is completed, so that the access to said data storing part is stopped, to allow said data to be written to accumulate in said data storing part, and wherein said write-in controlling part detects information showing an end write location based on absolute location information showing an absolute location of a blank area that is formed on the optical disk beforehand.
