From the SONY Website:

"It features enhanced Digital Audio Extraction and a unique Dual Speed operation."

"The Auto Balancing Spindle reduces vibration produced through disk wobble. Performance is improved while noise, mechanical wear and CPU utilisation is reduced."

This drive helps to overcome the noise/vibration associated with out-of-balance audio discs when used in CDRom drives.

Better sound, less noise!

Only for use on REMOTE Controlled CDplayer models
