Abstract

810,111. Magnetic recording and reproducing apparatus. NEWMAN, J. E. May 10, 1955 [Feb. 10, 1954; May 10, 1955], Nos. 3939/54 and 13560/55. Class 40 (2). In a magnetic record apparatus having means for producing relative movement of the record medium at two different speeds, means responsive to signals reproduced at the higher of said two speeds initiates a control action and is adjustable to operate upon receipt of any selected number of said signals. The apparatus comprises a magnetic tape recorder having a tape on which subsonic signals are recorded between each sound passage, the frequency of the said signals being too low for the amplifier to detect at normal speed, but on fast winding the signals are raised in frequency and become audible and amplifiable. A given number of such signals, received at the grid of a valve Vp via a pair of contacts DP closed during fast winding, cause the application of brakes and the switching of the apparatus to " reproduce," in accordance with the setting of preselector contacts 1 to 7, inclusive.
