Optical information recording device |
摘要 |
An optical information recording device is suitable for detection of deviation between a strategy and a record pattern. Test record is performed on an optical recordable medium using a predetermined strategy. A binarization signal that is obtained by reproducing the test record result is counted. A pit length and a land length included in the binarization signal are specified using a histogram of the count result. A plurality of the reproduction patterns is searched and extracted from a record area based on the pit length and the land length. Deviation between a strategy and a record pattern formed by the test record is detected through comparison of the obtained reproduction patterns through the search.
