Optical disc recording/reproducing apparatus having automatic protection of previously recorded data

A disc recording/reproducing apparatus, comprising:

• recording means for storing compressed input digital data in a memory, reading a burst of said digital data from said memory, recording said digital data to a data area on a disc, and recording position information of the recorded data in a lead-in area disposed on an innermost peripheral portion of said disc;
• and
• reproducing means for reproducing data from said disc on the basis of said position information, storing the data in said memory, reading the data from said memory at a constant rate, expanding the data, and outputting the data, pausing reproduction in response to a pause command, and outputting a position signal indicating a pause position where reproduction has been paused,
• means for moving said recording head to said pause position indicated by said position signal and starting a recording operation for said input data from said pause position when said record commanding means commands a start of recording operation while said reproducing operation is paused.

A disc recording.backslash.reproducing apparatus, comprising:

• recording means for storing compressed input digital data in a memory, reading a burst of said digital data from said memory, recording said digital data to a data area on a disc, and recording position information of the recorded data in a lead-in area disposed on an innermost peripheral portion of said disc;
• and
• reproducing means, including a reproducing bead, for reproducing data from said disc on the basis Of said position information, storing the data in said memory, reading the data from said memory at a constant fate, expanding the data, and outputting the data,
• reproduction commanding means for commanding a start of a reproducing operation by the reproducing means and for moving said reproducing head to a start position of a digital data stream and starting a reproducing operation for said digital data stream from said start position when said reproduction commanding means is activated for the first time after said digital data stream has been record and a record operation is paused.
