A method and a system for adjusting optical recording device involving an optical recording medium of non-uniform heat characteristics

摘要

The discrepancies in the input-output operations associated with utilizing predetermined optical disk portions with various heat capacities (such as land portions and groove portions) to store data are substantially reduced by providing additional and separate information (such as values used in the operational parameters for adjusting laser strength or filtering characteristics of a waveform equalizer) to compensate the non-uniform characteristics. The additional data may be stored in an external memory or on the disk itself.
