We have newly developed an experimental digital VCR with small drum diameter, 26.7mm, by taking account of high density recording, cassette exchangeability, and the ability of multispeed playback. The VCR uses an overwrite recording technique without erasure heads, and a newly developed waveform equalizer for the reproduced signal, to achieves a recording density of 2.45μm^2/bit. During multispeed playback, a sufficient data acquisition rate is obtained to employ AGC (Automatic Gain Control) for the reproduced signal.
