ABSTRACT:
A method of performing data compression of audio data and sequentially recording the data on a disk in units of the data, each unit being formed of a predetermined amount of the data. In the method, there is provided a means for detecting a breakpoint of the audio data. The audio data is continuously recorded by joining, even at the breakpoint, the data preceding and subsequent to the breakpoint, thereby forming the unit data. A piece of information indicating the position of the breakpoint is recorded on the disk. When an operation to suspend or stop the recording operation has been made, the last data immediately before the suspended or stopped point is included in the unit data and recorded as a portion of the unit data. The following data is recorded started from new unit data. When the last recorded data is short of a unit data amount, the remaining portion of the unit data amount is filled with data of a special pattern.
