Title: Improvements relating to the magnetic recording of digital data
IPC: G11B20/14
Filed: 1962-08-27
Abstract: 1,017,583. Magnetic recording; digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 27, 1962 [Sept. 11, 1961], No. 32749/62. Headings G4C and G5R. To record binary digits with the resolution of saturation recording, but with the packing density of non-saturation recording, a sinusoidal wave form, Figs. 2(c) or 3(c) is phase-modulated 180 degrees at the transitions of a rectangular waveform, Figs. 2(a) or 3(a) representing the binary information. In Figs. 2, the binary value is represented by the signal level of the rectangular waveform. In Figs. 3, the binary value is represented by the presence or absence of a transition during the 360 degrees of one cycle of the originating sinusoidal wave. In either case, previous recordings are erased by saturating the medium in one direction prior to recording. The unmodulated carrier and the phasemodulated signal are recorded as adjacent tracks on a tape (Fig. 1, not shown) coding being achieved by selecting either the carrier or its phase-inverse by a logical gating system. To recover the information, the track outputs are fed into a gating system for comparison, the output being squared and limited in known manner to regenerate the original rectangular waveform. Instead of recording the unmodulated carrier, it may be derived from the modulated track for use in demodulation on playback. With the coding of Fig. 3(a), the direct, non-saturating, recording of this waveform on a drum may yield a pulse output on playback (Fig. 6, not shown) from which the recorded waveform may be realized by a pulse-amplitude detector.

Abstract: 855,992. Pulse delaying circuits. ERICSSON TELEPHONES Ltd. Oct. 16, 1958 [Oct. 21, 1957], No. 32833/57. Class 40(6). A pulse delaying circuit comprises two or more electro-mechanical delay devices to which the input pulses to be delayed are switched sequentially and separately the output pulses from the devices being combined to select a predetermined portion only of the delayed signal. In this way the distortion associated with the use of electro-mechanical delay devices is avoided. Fig. 1 shows the logical diagram of a pulse delay device in which input pulses at 17 are amplified at 18 and applied selectively and sequentially through AND gates 19, 20 to amplifiers 23, 24 respectively. The AND gates are opened sequentially by clock pulses from generators 21, 22 so that the pulses at amplifiers 23, 24 are at half the pulse repetition frequency of the input pulses at 17. The amplifiers 23, 24 feed electro-mechanical delay devices 10, 11 respectively the delayed pulse outputs of which are applied to amplifiers 25, 26 and combined in AND gate 27 the output of which is shaped, limited in unit 28 so that selected portions only of the signal are produced as a delayed pulse signal on lead 29. Suitable amplifiers and limiters are described with reference to Fig. 2 (not shown). In a modification shown in Fig. 3 the input pulses at 17 are applied via OR gates 54 to AND gates 19,20 and thus to electro-mechanical delay lines 10,11. The AND gates 19, 20 are opened by clock pulse generators 21, 22 as previously described. The outputs from the delay lines 10, 11 are combined in unit 27 which comprises pulse lengtheners and reshapers 55, 56 and AND gates 57, 58 which are opened by clock pulse generators 59, 60 the pulses from which respectively determine the leading and trailing edges of the output pulses on the line 29. The output pulses from the combining unit 27 are further shaped and lengthened by units 28 controlled by clock pulse generator 28<SP>1</SP> the output pulses on line 29 may be recirculated to the input through OR gate 54.
