Method and apparatus for controlling data recording speed in an optical disk device

摘要

The present invention relates to a method and apparatus that can control data recording speed such as in an optical disk device. Based on a number of occurrences of recording failure such as buffer underrun, a method and apparatus can either reduce a data recording speed or dynamically changes the speed to a pre-defined speed while recording input data onto a writable optical disk. Therefore, even if a user-selected data recording speed is higher than the transfer rate of the external input data, the data recording speed can be controlled to efficiently complete a data recording operation or operate at a more desired data recording speed.
