Recording power adjustment for optical storage apparatus |
摘要 |
After a first test pattern and a second test pattern were sequentially test written to at least two adjacent tracks by a light emission driving of a laser diode, the adjacent track in which the first test pattern was first test written is reproduced, thereby checking the presence or absence of a data error. When there is the data error, the test writing is repeated while changing a light emitting power until the data error is eliminated. When there is no data error, the light emitting power used in the test writing is set to a recording power.
