Title: Method of and device for recording and reproducing on magnetic carriers at any speed
IPC: G11B5/00
Filed: 1956-10-04
Abstract: 799,173. Magnetic recording and reproducing apparatus. SOC. ASSERVELEC. Oct. 4, 1956 [Oct. 17, 1955], No. 30247/56. Class 40 (2). A method of magnetically recording and reproducing frequencies on a magnetic carrier for operating relays to carry out unspecified control operations, comprises the steps of recording on a carrier 4, in accordance with a predetermined code, frequencies from a preliminary disc record 1 moving in fixed speed relationship to the carrier 4, subsequently picking up and feeding the recorded signals to the grids of mixing valves 51, 52, 53 having other grids to which are individually applied the different constant frequencies from a preliminary disc record identical to disc record 1, but said disc being rotated at a speed corresponding to the algebraic sum of the original recording speed and a constant reference speed, whereby difference frequencies are detected by tuned circuits of the said valves to operate the associated relays 61, 62, 63. During the recording operation, motor M2 drives the carrier 4 through bevel gears and roller 8, and the disc 1 through a differential gear 3, a second motor M1 connected to the said differential gear being stationary during this operation and the switches 10, 11, 12 and 13 being in the right-hand position. Frequency signals are recorded through an amplifier A. on to the carrier 4 when keys 31, 32, 33 are operated. During reproduction of the signals, the switches are in the left-hand position and the signals from the carrier 4 are fed via head To to the grids of mixing valves 51, 52, 53. At the same time motor M1 is set in motion to rotate disc 1 and thereby frequencies relatively different to the frequencies originally recorded are produced which. when fed individually to second grids of the mixing valves 51, 52, 53 produce difference frequencies which operate relays 61, 62, 63. Specifications 783,089, 787,672 and 795,985, [Group XIX], are referred to.
