Abstract

1491600 Magnetic sheet record players GAKKEN CO Ltd 29 Oct 1975 [11 Dec 1974 25 Feb 1975 27 Feb 1975] 44568/75 Heading G5R A magnetic sheet 200 having a spiral record track thereon is clamped at its edges between a rectangular holder frame 30 and a rectangular platform 27 in which rotates a turn-table 50 carrying a magnetic head 100 which moves along a radial guide slot 52 in the turntable 50 so as to follow the spiral record track, the head being yieldably urged against the sheet 200, e.g. by a coil spring 109, Figs. 8 and 9 (not shown). The operative face of the head 100 is slightly tilted forwards and outwards.
