Abstract
1,059,069. Data storage discs. RECOGNITION EQUIPMENT Inc. Dec. 13, 1965 [Feb. 11, 1965], No. 52806/65. Heading G5R. A magnetic disc, particularly for storing digital data, has circular or spiral grooves 22 of rectangular cross-section in a highly permeable body with the recording material mounted on at least one of the curved groove surfaces by bonding material of high reluctance. As a result, stray magnetic fields follow preferentially the dotted lines with benefit to the permanence of the recording. One of the grooves in Fig. 2 may carry a clock track or the edge of the disc 56, Fig. 5, may be serrated to form a modulated permeability track. The disc is mounted on an associated record/ playback machine (not detailed) by means 18, 20 and at other times may be attached, in ” dog-tag ” fashion, to military personnel or machines by a chain, Fig. 5.
