A teaching machine on which is replaceably mounted a rectangular sheet of paper or the like with a spiral magnetic track on one surface, which is directed downwardly, and with printed material on the other surface for visual presentation of the subject of audio information prerecorded on the track. A movable magnetic head under the sheet follows its track for playback or recording. To afford closer contact between head and sheet and hence to improve the playback quality, a hinged holder frame secures the sheet to the machine casing at its marginal edges only, and the head is spring biased into abutting contact with the yieldably supported sheet. The head itself is supported out of the perpendicular to the plane of the sheet so as to remain in intimate contact therewith throughout its travel along the complete track on the sheet.
In a magnetic sheet player of the type having a casing with a rectangular platform for supporting a magnetic sheet thereon, said magnetic sheet having a spiral magnetic track on one surface which faces said platform, a turntable constituting a part of said platform and rotatable relative to the same, and a magnetic head movable along a radial guide slot in said turntable in step with the rotation thereof to follow the spiral track on the magnetic sheet, the improvement comprising:
