Title: Magnetic tape recording device
IPC: G06K7/10
Filed: 1958-09-12
Abstract: 854,159. Checking arrangements for magnetic data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. Sept. 12, 1958 [Sept. 19, 1957], No. 29260/58. Class 106 (1). [Also in Group XVI] A typewriter or accounting machine 18 transmits pulse-shaped information which is stored and also recorded in a magnetic tape 4, the record in the tape being read after each line and checked against the information on the store. The information is grouped in predetermined maximum number of characters and recorded on a definite length of the magnetic tape 4 by a writing-reading head which is mechanically moved forwardly and backwardly so that characters recorded are read and compared with the input information recorded in the store: only in the absence of errors is the magnetic tape advanced automatically by the definite length. This length is identified by photo-electric sensing device 8 reading transparent marks attached to the tape, and the tape is advanced one line-length at a time but during writing and reading the tape remains unmoved. Alternatively, when shorter linelengths are to be recorded character counting means may be provided. The information typed is first passed through a code connector 21 and then stored in either of two flip-flop register, temporary storage devices 19, 20 which are alternately in use. A further storage device 22 serves the writing in of fixed data. The storage devices are connected to a mixing device 23 which reads and counts the words contained in the store 22 and transfers them to the magnetic head of the recording device 1. After the information is recorded the head returns and makes a second travel to read the just recorded information and this is entered in a comparator 35 comprising diodes 36 and transistor 37, Fig. 4. If the information from the magnetic head is different from that coming from the mixing device 23, the latter communicates its information again to the magnetic head which, in turn, registers the information, reads it again, and again routes it to the comparator 35. An alarm is given if there is still no comparison.

Abstract: 1329787 Videotapes; recording and playback SONY CORP 24 June 1971 [26 June 1970] 29681/71 Heading G5R In a videotape recording/playback system usable for editing, an unwanted section of a recording is erased by a portion of the actual signals that are to be recorded in its place. In the embodiment shown, video signals which are desired to be added to a tape (6, Fig. 1, not shown) are fed from a modulator 8, Fig. 3, to two rotary recording heads 3a, 3b, and the high frequency portion of these signals, as selected by a high pass filter 19, is simultaneously fed as erase current to two similarly rotating erase heads 4a, 4b. Heads 4a, 4b are arranged to scan the same tracks as heads 3a, 3b, and in advance, as in Fig. 2, but their gaps are set obliquely to the normal recording field direction. Thus by suitably amplifying the erase currents at 14, Fig. 3, the erase fields can be made to saturate the recording medium in the oblique direction, i.e. to wipe out the previous recording, and by carefully choosing the values of the track width, the erase field offset angle, the frequencies, &c., it is possible to make the erase signal produced in normal replay of the edited tape very small.
