Abstract
An improved method and apparatus for transferring data in a CD-ROM system. The CD-ROM system includes a buffer manager for identifying the capacity of a buffer memory used to store data from a disc. The buffer manager controls the transfer of data into and out of the buffer memory. Each time a sector of data is transferred from a disc into the buffer memory, a counter is incremented to track the amount of data in the buffer memory. If the counter equals the capacity of the buffer memory, the transfer of data from the disc is halted. Further transfer of data is not allowed until buffer memory is available.
