WRITABLE OPTICAL DRIVE WITH DYNAMICALLY VARIABLE LINEAR VELOCITY TO PREVENT BUFFER UNDER-RUN |
摘要 |
The present invention relates to methods and apparatus for dynamically varying a linear velocity of an optical drive during a write operation to an optical disc to reduce the likelihood of a buffer under-run event. By reducing a linear velocity and writing speed while the optical drive writes on the disc, an embodiment of the invention preserves the buffer and reduces a minimum data transfer rate required to sustain writing to the disc for a sustained period of time. The basic components of one embodiment of a CD-RW drive (100) in which the present invention may be implemented include a controller (110), a microcontroller (112), a nonvolatile memory (114), which stores firmware (116) executed by the microcontroller (112), a buffer (118), a spindle motor (120) and an optical pick-up (122).
