Abstract
1505917 Recording and playback P BADENHOP and M HEMMERLING 10 Oct 1975 [12 Oct 1974] 41697/75 Heading G5R The discrete video signals recorded on each transverse track of a recording medium 3, e.g. optical or magnetic, are simultaneously detected 4, stored in an intermediate store 5, and then sequentially read 6 from this store in the chronological sequence in which they were first recorded in the medium 3. In Fig. 1, the record medium 3 is of an optical tape which is moved past a narrow beam of light and a linear array of LCD elements. In Fig. 3, the record medium 13 is a magnetic tape and is moved past a magneto-optic drum 14 which simultaneously detects and stores each transverse track of video signals on the tape 13, the signals being sequentially read from the drum by a scanned linearly polarized light beam from a laser 11.
