Abstract

The tape recorder has a writing element (11), in contact with a magnetic tape (10), having a non-magnetic pressure bearing (16) around the end part of a narrow reading stylus (13). The tape (10) and the writing element (11) may be displaced w.r.t. each other. The bearing (16) provides a sliding face which is adapted to that of the tape (10) and which has a much greater area than that of the stylus. The bearing is maintained permanently against the tape and lubricated so that tape wear is avoided. The stylus may be a ferromagnetic wire with an end face of diameter 0.1 to 0.3 mm.
