Abstract
975,978. Disc record data storage apparatus. IBM WORLD TRADE LABORATORIES (GREAT BRITAIN) Ltd. Jan. 10, 1963 [May 22, 1962], No. 19590/62. Heading G5R The description of Figs. 1-5 is the same as in Specification 975, 979, but the claims are directed to the means for incrementally processing successive tracks. The description extends to multi-head embodiments providing continuous recording:- Fig. 6 requires slip-rings for the heads, but only one drive means for the heads; Figs. 7 and 8 require three drive means but no slip rings since the partial tracks do not overlap. Fig. 9 is equivalent to the single-head embodiment in Fig. 5 (not shown, but see Specification 975,979). Stacked assemblies of discs with relevant heads and common drive means may be used, particularly where the information on the discs is related in decade manner. The heads are preferably of the type supported over the discs by Bernonilli effect.
