Abstract: 820,663. Recording &c. heads &c. DECCA RECORD CO. Ltd. June 23, 1958 [March 21, 1957], No. 9278/57. Class 40 (2). Multi-track heads with collinear gaps and windings so positioned on the stacked cores that coupling between the windings on adjacent cores is reduced. Exploded perspective views of three embodiments of the invention are given in Figs. 1-3. In Fig. 1, the cores are assembled from identical halves 10, 11 and the windings 16 on alternate cores arranged toward opposite ends of the side members 13. On closing up the stack, windings on consecutive cores will avoid one another mechanically and a reduction of magnetic coupling between the windings resulting in " cross-talk " is claimed. In Fig. 2, differing pairs of core-elements 20, 21 are stacked with their gaps in line but with alternate cores reversed about a plane through the gaps so that the windings 28, which in this case occupy the full length of the side-members 24, avoid one another in a sense perpendicular to the Fig. 1 arrangement. In Fig. 3, the core arrangements of Fig. 2 are associated with the winding arrangements of Fig. 1 so that the pattern of stacked cores and windings repeats itself at each fourth element.
