Abstract

802,481. Magnetic recording, reproducing and erasing heads. MARRIOTT, P. A. March 20, 1955 [Feb. 23, 1954], No. 5315/54. Class 40 (2). A sound head for recording, reproducing or erasing in a magnetic recording and reproducing apparatus comprises two lengths 1, 2 of magnetic material mounted side by side and one or both of which is either bent or hollowed out for a small proportion of its length at only one end so as to form at that end, between the lengths, a central space through which a winding or windings 4, 5 pass. The main body of the material serves as a handle or extension to facilitate handling during winding and assembly, and it may be used for fixing the head in position and supporting electrical leads, or it may be cut off after final assembly. Fig. 3 shows the head embedded in an electrical insulating material 7 enclosed in a sleeve 8. In another embodiment, not shown, the lengths are laminated.
