An optical disk unit includes the following: a storage part temporarily storing data to be written to an optical disk; a processing part processing the data; an encoder part modulating and outputting the processed data; a writing control part controlling writing of the data to the optical disk; and a writing command part detecting an occurrence of a state of suspension of supply of the data to the storage part and providing an operation command to the writing control part in accordance with the detection result. In the case of suspending the writing of the data to the optical disk, the writing control part causes the processing and encoder parts to stop accessing the storage part by setting the processing and encoder parts in a wait state after the processing and encoder parts access the storage part, and causes the storing of the data in the storage part to be stopped.
