Abstract
Multi-rate optical disc recording method and apparatus wherein data are recorded on the optical disc in accordance with a transfer rate of data, thereby preventing an unnecessary waste of a storage area in the optical disc and also enhancing a recording time of the optical disc. Said method and apparatus exploit a transfer rate detector for detecting a transfer rate of a digital signal generated at a digital signal source. This transfer rate detector allows a rotation velocity controller to rotate the optical disc at a speed corresponding to the transfer rate of the digital signal, in response to the transfer rate of the detected digital signal. Also, the transfer rate detector allows a recording portion to record the digital signal on the optical disc at the detected transfer rate.
