ABSTRACT:
This optical disk device includes a read means which reads data from an optical disk upon which data is recorded at a variable bit rate for each sector. Moreover, this optical disk device includes a buffer memory which sequentially stores data which has been read by the read means, and a replay means which sequentially reads out and decodes data stored in the buffer memory, and replays that data. Furthermore, this optical disk device includes a control means which, when a command for special replay is issued, calculates the address of the sector currently being decoded by the replay means based upon the address of the sector currently being read by the read means, and upon the amount of data stored in the buffer memory. And the control means commands the read means to read out, from the optical disk, a sector to be jumped to.
