    copy signal input means for generating a copy signal indicative of user selection of a copy mode;

    control means operably connected to said mode signal input means and said copy signal input means, for producing servo control signals to enable a playback mode of said second video cassette deck and to enable a record mode of said first video cassette deck in response to receipt of said copy signal when said first mode selection signals are indicative of a record pause mode of said first video cassette deck and said second mode selection signals are indicative of one of a playback mode and a still mode of said second video cassette deck, and for producing said servo control signals to enable a record mode of said second video cassette deck in response to receipt of said copy signal when said first mode selection signals are indicative of a stop mode of said first video cassette deck;

    first motor driving means, connected to receive said servo control signals, for controlling driving of said first video cassette deck in response to said servo control signals; and
