Summary:An optical media playback device includes a memory to store calibration data specifying how a mark of a particular length should be formed on an optical storage media. A control module writes a training pattern onto the optical storage media based on the calibration data. The training pattern includes a first mark having a first length. A control module reads the training pattern previously written onto the optical storage media and determines whether the first length of the first mark corresponds to the particular length specified by the calibration data. The control module adjusts the calibration data stored in the memory in response to the first length of the first mark not corresponding to the particular length specified by the calibration data.
