Abstract
A division test write processing unit is provided and a test writing process for deciding an optimum light emitting power by executing a test writing on a medium is divided into a plurality of division test writing processes. When an upper command is received, in the division test write processing unit, a division control unit skips to a division executing unit locating at the head of the processes which are not yet executed among a plurality of division executing units and allows the dividing processes of the test writing to be executed for a predetermined time.
Claims30
An optical storage apparatus comprising:
- a light emitting power adjusting unit for adjusting a light emitting power of a laser diode which is used for recording and reproduction of a medium;
- and
- a division test write processing unit which executes individual test processes independently at intervals, said test processes being divided into at least two test writing processes;
- wherein said division test write processing unit includes:
- a plurality of division executing units which divide said test writing process into a plurality of processes and which also execute said plurality of processes;
- and
- a division control unit which discriminates the necessity of the test writing when an upper command is received, when the necessity of the test writing is determined, said division control unit skips the process to the dividing process locating at the head of the dividing processes which are not yet executed in said division executing unit, thereby allowing said dividing process to be executed for a predetermined time.
An optical storage apparatus comprising:
- a decision unit which decides to execute one of a sequential test write processes and a division test write process;
- and
- a test write executing unit which executes a decided test write process,
- wherein said sequential test write process executes individual test processes continuously and said division test write process executes individual test processes independently at intervals, said test processes being divided into at least two test writing processes.
