Abstract:
A disk storage device, wherein data is recorded onto a disk using an optical beam emitted from an optical head, comprising:a record decision unit for determining when to stop and start recording of data onto the disk; a record-start-position detection unit for detecting a record-start position from which additionally writing recording data on the disk starts when said record decision unit judges a start of recording of recording data; a synchronous setting unit for reading data recorded onto a disk before a halt of recording when said record decision unit judges a start of recording of recording data, and for synchronizing recording of additional data to be written with the already recorded data; a record-status detection unit for reading data recorded on the disk before a halt of recording every time said record decision unit judges a halt of recording and then detecting the formation status of recorded data; and a head output controller for setting the luminous output of said optical head at the time of starting according to the recording state detected by said record-status detection unit.
