Abstract

758,608. Magnetic recording and reproducing apparatus. GENNING, E. Sept. 8. 1954 [Sept. 8 1953], No. 25986/54. Class 40(2) In a magnetic wire record apparatus, a detachable cassette 14 carries axially freely mounted spools which are loosely located by peripherally spaced pins and is adapted to engage a reversible drive and a magnetic head 21 on the main part 22 of the apparatus, and incorporates a spring bow 24 which presses the wire 17 into contact with said magnetic head 21. When the cassette is withdrawn from the machine the spring bow 24 holds the wire 17 against an elastic bedding 27 so that it is retained in position between guide pins 26. At the same time the spools which are loosely located in position by pins 18 are held from rotation by the ends 30 of a flat spring 29 which are lifted by pins 20 when the cassette is replaced on the machine. The spools 15 16 may have incorporated therein magnetic slip couplings as shown in Fig 4. A detachable strip 46 may be provided on the outside of the cassette to provide indication of duration of recording.
