Abstract
An optical medium storage device improves the usable life of re-writable optical storage mediums, such CD-RW, DVD+RW and DVD-RAM disks, by adjusting write parameters to compensate for time between an initial write on the optical storage medium and the current time, with adjusted write parameters fine-tuning signal-to-noise ratios and improving the number of reliable overwrites for the optical storage medium. A time compensator determines the time delta between an initial write on the optical storage medium, such as formatting of the medium, and the current time, and then applies the time delta to determine a time compensation factor that adjust the write parameters of a focused laser beam that writes information to the optical storage medium
Claims10
An optical drive for interacting with an optical medium, the optical medium having an area allocated for use by the manufacturer of the optical medium, the optical drive comprising:
- an optical pickup unit operable to illuminate the optical medium with a laser and to read light reflected from the optical medium as information, the information comprising a time stamp stored in the area allocated for use by the manufacturer of the optical medium.
A method for interaction with an optical medium, the method comprising:
- illuminating an area of the optical medium allocated for use by the manufacturer of the optical medium;
- and
- reading a time stamp from illumination reflected from the area of the optical medium allocated for use by the manufacturer of the optical medium.
An optical medium comprising:
- material having reflective properties readable by illumination of a laser;
- and
- an area allocated for use by the manufacturer of the optical medium;
- and
- a time stamp stored in the area allocated for use by the manufacturer of the optical medium.
