A tape recorder and reproducer machine has a rotatable head drum carrying a plurality of heads for recording a signal onto a cassette-type magnetic tape and for reproducing the signal recorded on a cassette-type magnetic tape. The machine comprises a cassette chamber for receipt of a tape cassette, a protective member movable between first and second positions, and a drive for moving the protective member to the first position between the cassette chamber and the head drum to protect the head drum from damage when the tape cassette is to be placed into or discharged from the cassette chamber. The drive moves the protective member from the first position to the second position allowing access from the head drum to the magnetic tape when the tape cassette is received in the cassette chamber.
