ABSTRACT:
The present invention provides an improved disc drive. In one embodiment of the present invention a disc drive capable of spinning a disc, which contains more than one type of data is disclosed. A first type of data is associated with a first speed, and a second type of data is associated with a second speed that is faster than the first speed. The disc drive includes a drive mechanism, which may spin the compact disc at the first and second speeds and retrieve data from the compact disc at either speed. The disc drive also includes an elastic buffer, which is in communication with the drive mechanism. The buffer receives data from the drive mechanism at a variable input data rate and outputs data at a variable output data rate. Whereby when the drive mechanism spins the compact disc at the second speed the buffer may receive the first type of data without causing the drive mechanism to slow down to the first speed, and the buffer may output the first type of data at the variable output data rate. Preferably, the variable output data rate is a first data rate that is associated with the first format.
