    a keyboard having a record key and a playback key;

    a control circuit coupled responsively to said keyboard;

    a memory unit coupled responsively to said control circuit, said memory unit having a medium for storage of information, said storage medium having structure which enables substantially random access to information stored in said medium for retrieval of the stored information from said storage medium;

    at least one input, said input being connected to a user'"'"'s audio/video program signal source and also being coupled to said memory unit so as to enable program information presented by the signal source to be transferred to and stored in said memory unit; and
