Abstract
1,205,349. Magnetic recording and playback. SPERRY RAND CORP. 2 Jan., 1969 [3 Jan., 1968], No. 283/69. Addition to 1,205,347. Heading G5R. In a system of the type described in Specification 1,205,347, the profile of the flexible record strip 42, 44, 46 or 48 is flattened by means of a vacuum mechanism 40 which removes a portion of the boundary layer of air between the record strip and the rotor 22. The vacuum mechanism is controlled by means of a valve (58, Fig. 1). The free end 42
