Abstract
A method and apparatus for recording onto or playing back from a magneto optical disk eight channels of digital audio data. Eight channels of serial audio data, for example in a AES/EBU format is converted to parallel data and provided to one or more buffers via a DMA controller. After buffering, the data may be recorded onto a MO disk via an SCSI.
Claims6
An apparatus for recording and playing back digital audio signals comprising:
- input means for providing a plurality of channels of digital audio signals;
- buffer means for storing digital data signals;
- a direct memory access (DMA) controller for coupling the plurality of channels of digital audio signals to the buffer means;
- a magneto optical disk drive;
- and
- a small computer system interface (SCSI) for operatively coupling the MO disk drive with the DMA controller;
- wherein the plurality of channels of digital audio signals is stored by the buffer means and provided to the MO disk drive;
- wherein the input means includes means for converting the plurality of channels of audio data from serial data to parallel data;
- and
- wherein serial data is provided to the apparatus in AES/EBU format.
