发明名称 Method and apparatus for multi-channel recording and reproducing
摘要 <p>In a magnetic recording and/or reproducing apparatus, when the reproduced audio data is processed in the reproduction system and the record system and is re-recorded in every cycle of N times the cycle during which the reproducing magnetic head scans a pair of recording tracks, the recording magnetic head is positioned behind the reproducing magnetic head for 8.5 + 4N track pitch so that the reproduced audio data can be re-recorded on the original recording track, therefore a write-after-read processing can be realized. Further, in the recording magnetic head positioned behind the reproducing magnetic head for the specific track pitch, the audio data is stored in a memory circuit for time base compression or expansion with a multichannel mode such as to record the reproduced audio data at the same part on the magnetic tape, so that a magnetic recording and/or reproducing apparatus which enables to perform the write-after-read processing can be obtained with simple construction if the number of channel is switched. Furthermore, the 2<n> channel audio data is recorded by interleave processing in every cycle of N times the cycle forming a pair of recording tracks, so that even when the cycle during which a pair of recording track is formed is not kept to a multiple of integer of sampling cycle, a magnetic recording apparatus and a magnetic recording and/or reproducing apparatus which record and reproduce a plurality of channel audio data can be provided. <IMAGE></p>
