摘要： An object of the present invention is to provide an optical recording/reproducing apparatus capable of improving medium usability through a laser power adjusting process while keeping compatibility with a read only type medium. The optical recording/reproducing apparatus adjusts laser power using a PCA till the PCA is used up. After the PCA is used up, an additional area is reserved at the outermost circumference position, thereafter when the additional area is used up, a new additional area is reserved at an inner circumference side of the used up additional area to adjust laser power. The additional area is reserved at an outer circumference than a lead-out area, and therefore format compatibility with a read only type optical disc can be maintained. The additional area is reserved only when the PCA is used up, thus capacity compatibility with a read only type optical disc can be maintained while laser power is adjusted with only the PCA.

摘要： In an optical disk recording method of recording data onto a recordable optical disk which includes a data zone where data is recorded and a management data zone where management data indicating the recorded part of the data zone is recorded, an extended management data zone in which the management data is to be recorded is set in the data zone in response to an extension instruction.

摘要： When a record decision unit 22 judges that recording has been interrupted, the recording data in a predetermined frame is ended. Data are continuously recorded onto a disk until the frame synchronous signal duration following the predetermined frame. Thereafter, the control output generated from the head output controller 14 is controlled to interrupt the recording operation. When the record decision unit 22 judges the resuming of recording, the control output from the head output controller 14 is controlled to resume the recording operation onto the disk from the frame synchronous signal duration in which the recording of data onto the disk has been interrupted.
