Abstract

Abstract A data recording/reproducing apparatus uses a single recording medium (1) in which absolute address data are previously formed. Also, the data recording/reproducing apparatus has a first memory (21) for recording and a second memory (14) for reproducing. Audio data reproduced from the recording medium (1) is stored in the second memory (14) at a first transfer rate, and the audio data stored in the second memory (14) is sequentially read at a second transfer rate lower than the first transfer rate to be audio-reproduced, while audio data inputted from external is sequentially stored in the first memory (21) at the second rate and the audio data stored in the first memory (21) is read at the first transfer rate to be recorded on the recording medium (1). The aforementioned reproducing and recording operations are alternately repeated. Thus, the data recording/reproducing apparatus allows audio data recording operation to be concurrently performed during audio reproduction with the single recording medium (1). <IMAGE>

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 197 words
A data recording/reproducing apparatus for recording and/or reproducing audio data onto or from a recording medium (1) having absolute address data, the apparatus comprising: a first memory (21) for recording; a second memory (14) for reproducing; a first reproducing means (3, 9) for reading audio data on the recording medium (1) by the block and storing them in the second memory (14) at a first transfer rate; a second reproducing means (15) for sequentially reading the audio data stored in the second memory (14) at a second transfer rate lower than the first transfer rate and sequentially outputting them; a first recording means (20) for sequentially storing audio data, which is inputted from external, in the first memory (21) at the second transfer rate; a second recording means (22, 24) for reading the audio data stored in the first memory (21) at the first transfer rate and recording them in the recording medium (1) by the block; and control means (10) for controlling so that writing operation into the second memory (14) by the first reproducing means (3, 9) and reading operation from the first memory (21) by the second recording means (22, 24) are alternately repeated.
Claim 2
Dependent Claim 23 words
The data recording/reproducing apparatus as claimed in claim 1, the controlling means (10) includes means for instructing simultaneous operation of reproduction and recording.
