Abstract:
A method and apparatus for controlling reproduction speed of an optical disk are provided. The method for controlling reproduction speed of an optical disk includes checking whether a read command has been received, and examining whether the received read command is intended for performance evaluation based on the number of backward track jumps of a laser beam irradiated on the optical disk. The method and apparatus for controlling reproduction speed of an optical disk provide designed read performance when an external host executes a performance test.
