- What will happen with Yamaha CDR-W drives?
The CRW8824 supports both standards above. Yamaha plans, in order to show the capability of high speed ReWriting, to print a special logo "High Speed RW" on a surface of the recorder. The recorder having this logo is able to use the high speed ReWitable CD.
