<p>During a 'Burst Read Mode', an optical storage device reads data from a medium into a buffer faster than a host device reads data out from the buffer. To improve power efficiency, the optical storage device powers down read/write components when a buffer fills to a first level. While the read/write components are powered down, the host device continues to read data out of the buffer. When the output buffer empties to a second level, a buffer logic wakes up the system microprocessor and the system microprocessor powers up the read components. During a 'Burst Write Mode', the host device reads data into the buffer slower than the optical storage device reads data out from the buffer to write the data to medium 3. To improve power efficiency, the optical storage device powers down read/write components when the buffer empties to a third level.</p> |
