Title: Improvements in devices for recording information on a magnetic support, in particular on a multitrack magnetic tape, and for reading the information thus recorded
IPC: G11B20/18
Filed: 1964-01-10
Abstract: 1,038,114. Magnetic tape data storage. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 10, 1964 [Jan. 15, 1963], No. 1290/64. Heading G4C. Binary data is recorded in parallel in phasemodulation form on magnetic tape by reading it into registers B, Fig. 1 (not shown), one for each binary order (two orders only shown) and gating out the signals b and #b with clock signals a, #a changing polarity every bit time, so that polarity changes representing the bits in B are effected at the outputs of " exclusive- or " circuits C. The clock signals m are used to derive pulses k for resetting the input registers B and consequent derivation of the a, #a pulses in a pilot generator A. A reference (clock) signal is also recorded by head N alongside the data channels recorded by heads J. The reading of information so recorded results in a positive or a negative pulse on each channel at the bit time, and apparatus for registering these pulses and deriving clock pulses is described in detail. The non-existence of a pulse on any channel indicates error, and this may be detected by a system of " and " gates. Transistor circuits comprising threshold gates, emitter followers, amplifiers and bi-stable and monostable flip-flops for all the units are described and illustrated.
