Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain continuous reproduced sound while conducting an n-fold speed reproducing of digital audio signals recorded in a helical track in frame synchronized with digital video signals using a DT head. SOLUTION: During recording, a CH1 records digital audio signals that are delayed equivalent to one frame on a CH5 that is made a pair with the CH1. When a two-fold speed reproducing is conducted, traces are conducted by the DT head for every other track. Thus, at the CH1 and the CH5 that are made into a pair during a recording, frames F1, F3, F5, etc., and F0, F2, F4, etc., are respectively reproduced. During each frame interval, signals equivalent to two frames of the CH1 and the CH5 are thinned in a prescribed manner, for example to make the signals having the number of samples equivalent to one frame and outputted as the signals of the CH1. Thus, the signals of the CH1 during a recording are reproduced with a two-fold speed and pitch and sound feeling, in which audio signals recorded in a longitudinal track with an analog system are reproduced with a two-fold speed, is obtained.
