Abstract: 1452816 Thermomagnetic recording PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 May 1974 [1 June 1973] 23770/74 Heading G5R Apparatus for recording on a magnetic record medium, provided on an elongate carrier 1 and having a temperature dependent coercive force, has a magnetic head 9 mounted on a rotatable support 4 for movement in a direction at an angle to the direction of movement of the carrier 1 which can be wrapped around a cylindrical surface of the support 4, and a radiation source 18 for producing a concentrated energy beam for locally heating the record medium, said beam being arranged to move in synchronism with the movement of head 9 and being directed on to a part 21 of the record medium which is about to co-operate with the head 9. A video tape recorder has a tape 1 wrapped through about 360 or 180 degrees, around a helical scanner 2 having one or two magnetic heads 9. The beam 19 from source 18, which may be a laser, is focused on to a spot 21 by a system of lenses and a mirror, or by mirrors of which mirror 20 is mounted on rotating drum 4. In alternative forms, the source 18 is mounted on the rotating part of the scanner 2 and, in the case of two heads 9, 180 degrees apart, one head may cooperate with light from the front of a laser source and the other head may co-operate with light from the back of the laser; the invention may also be applied to transverse scanning video tape recorders. The spot 21 may be 0À5 mm in front of the recording gap 10 of head 9 and may be wider than the recorded track but its dimension along the track length is less than or equal to the distance between the heating and recording points, e.g. 100 Î 300 Ám spot size. The output of source 18 may be controlled by a detector responsive to the radiation beam reflected from the tape. The apparatus may be used to record master tapes having a very high room temperature coercive force magnetic coating, e.g. Co-doped Fe 2 O 3 , or CrO 2  which may be modified to increase its coercive force, such tapes being copied by a conventional anhysteric copying process. To ensure that the oblique tracks of the slave tape copier are not mirror images of those required for normal playback, the tape wrap direction around the scanner 2 may be changed and the rotation of head(s) 9 reversed so that the master tape is recorded with oblique tracks which are mirror images of those ultimately required on the slave copies, Fig. 5 (not shown).

Abstract: 946,569. Magnetic data storage apparatus. OLYMPIA WERKE A.G. July 8, 1960 [July 15, 1959], No. 23931/60. Heading H3B. [Also in Division G4] A matrix of magnetic cores is arranged to receive information in a predetermined mode, sequence and speed and to read out in the same or a different mode, sequence and speed, according to the characteristics of the feeding and receiving apparatuses. Each core K is traversed by a half-write column conductor L 88 , Fig. 1, a half-write row conductor L zs , a half-read column conductor L SL  and a half-read row conductor L ZL . Coincidence of current in the write conductors switches a core on; coincidence in the read conductors switches a core off and simultaneously produces a pulse in an output conductor, Fig. 2. For serial-serial recording of information applied to terminal K 7  the elements of a stepping switch Sch s  are energized successively 1-30, the completion of each cycle stepping on a switch Sch z . Electronic switches S 1 -S 6  are operated appropriately to register 1 or 0 as the case may be whereby the first 6-bit character is registered in cores 1, 6, 11, 16, 21, 26 of the first line, and so on. For parallel-serial recording the elements of switch Sch s  are energized in groups I ... V. The information to be recorded is applied in parallel to terminals K 1 -K 6  to control switches S 1 -S 6 . For read-out switch S 7  is closed and switch Sch s  is set for serial or parallel mode as the case may be. Output pulses are generated on leads L 1 -L 6 , Fig. 2, to appear on terminals A 1 -A 6  for parallel operation or on terminal A s  for serial operation. Normally the system operates in forward sequence but by operating switch U 2  it can operate in reverse. If forward recording has been interrupted before the matrix is full, reverse reading out starts from the switch position last operative in recording. The switches Sch s  and Sch z  are as described in Specification 927,319.
