Abstract
A method and system for controlling the spin rate of an optical device. A device driver provides notification that media has been inserted into the optical device. A control service determines the format of information on the media. The spin rate of the optical device is locked or unlocked based on the format.
Claims12
A computer-readable storage medium having computer-executable instructions which, when executed, implement a method comprising:
- receiving a notification that media is inserted into an optical drive;
- determining a format of information on the media wherein the media includes data files and multimedia files;
- based on the format of the information, determining that a percentage of the multimedia files to data files is greater than or equal to a threshold;
- and
- upon determining that the percentage of the multimedia files to data files is greater than or equal to the threshold, controlling a spin rate of the optical drive by locking the spin rate of the optical drive to a spin rate compatible with the multimedia files, wherein the spin rate compatible with the multimedia files is less than a maximum spin rate of the optical drive.
