As a realtive newbie, I’m curious about the details of how WOPC works. How does the drive perform a recalibration? Why is it more meaningful than other previous recalibrations?
It was my weak understanding that there is some part of the media near the spindle which is reserved for OPC. Is this the area used by the WOPC process–which would only seem to compensate for ‘warming’ of the laser and the resulting power output
‘drift’ with time. Or is the calibration being done ‘inline’ and something is done so that the sectors are later ignored–like some of the copy protection tricks. This technique would seem to compensate for changes in the laser output and changes in the media. but, you’d lose some capacity–probably so little as to not matter, though.
For the curious among us, how does this work? Thanks for everything!
