System and method for removing noise when switching between heads in a digital video cassette recorder

An audio playback system for a video cassette recording comprising:

• a plurality of audio heads arranged on a drum and adapted to play back alternately audio signals recorded on a cassette tape according to a rotation of the drum;
• amplifying means for amplifying respective audio signals played back by the audio heads;
• filtering means for filtering amplified audio signals to separate each audio signal into audio signals corresponding to first and second stereo channels, respectively;
• digital demodulating means for digitally demodulating the audio signals corresponding to the first and second stereo channels;
• correction signal generating means for detecting a phase difference between the demodulated digital audio signals and generating a correction signal for correcting the phase difference;
• memory means for storing the demodulated digital audio signals temporarily, correcting an error caused by the phase difference according to the correction signal from the correction signal generating means and then outputting error corrected digital audio signals;
• and
• switching means for switching digital audio signals from the memory means to combine them into continuous digital audio signals each corresponding to each stereo channel, respectively.
