PURPOSE:To attain cross fade simply when a PCM data is recorded (reproduced) with a rotary type VTR by inserting a part of a data at the preceding frame of an audio data recorded obliquely onto a tape after the preceding frame while being doubled. CONSTITUTION:One frame's share of data 10a, 10b, 10c of the PCM audio data 10 are recorded sequentially to the 1, 2, 3 RAMs 9a, 9b, 9c. Then the PCM data 10a is read in high speed from the 1st RAM9a and recorded compressingly before the one frame's share as a data 10a', and the first storage data 11a-11b of the storage data 11 of the data of the 2nd RAM9b are read successively and recorded after the PCM data 10a' for one frame's share. Since the 1st RAM9a is idle in this state, the PCM data is written in succession to the 3rd RAM9c. The data at the preceding part of one frame is recorded insertingly after the preceding frame of the said frame by repeating the processing above. |
