Patent ID: 7038981

Claim:
A method for determining a record speed for recording audio data from a source optical media to a destination optical media, comprising: determining a maximum read speed for a source optical media device; setting the source optical media device to the maximum read speed; reading a first part of a first audio track on the source optical media; determining a digital audio extraction (DAX) speed for the first part of the first audio track; reading an end part of the first audio track on the source optical media; determining a DAX speed for the end part of the first audio track; selecting the slower of the DAX speed for the first part of the first audio track and the DAX speed for the end part of the first audio track; reading an end part of a next audio track on the source optical media; determining a DAX speed for the end part of the next audio track; comparing the DAX speed for the end part of the next audio track with the DAX speed for the end part of the first audio track; selecting the DAX speed for the end part of the next audio track when the DAX speed for the end part of the next audio track is less than or equal to the DAX speed for the end part of the first audio track; repeating the reading of the end part of the next audio track, the determining of the DAX speed for the end part of the next audio track, and the comparing of the DAX speed for the end part of the next audio track with the DAX speed of an end part of an immediately preceding audio track for each audio track on the source optical media; repeating the selecting of the DAX speed for the end part of the next audio track when the DAX speed for the end part of the next audio track is less than or equal to the DAX speed for the end part of the immediately preceding audio track for each audio track on the source optical media; and determining a recording speed for the audio tracks to the destination optical media using the selected DAX speeds.
