Abstract: The temperature of a magnetic head assembly is reduced by active heat transfer accomplished by a thermoelectric cooling element positioned between and in contact with the head assembly housing and the head assembly. The housing serves as a heat sink from which thermal energy is diffused.

Abstract: A multielement magnetic head is formed with a closure section having a nonmagnetic ceramic substrate on which a thin layer of magnetic ferrite is deposited and processed. The thin ferrite layer is cut to define the separate transducing elements and data track separation. The closure section is joined to a wafer formed from a ferrite substrate and a thin film conductive coil means.

Abstract: A single track magnetic head assembly comprises a nonmagnetic base, a magnetic layer disposed on one surface of said base, a nonmagnetic top closure positioned adjacent to an upper portion of said magnetic layer, and a magnetic bridge section positioned adjacent to the lower portion of said magnetic layer and below said top closure. A prewound coil is attached to the bridge section. The base, the magnetic layer and the top closure have arched sections to allow accurate definition of the throat height, and to enable testing of magnetic and physical properties of the magnetic head during the assembly process.

Abstract: A method of manufacturing a novel ferrite magnetic head assembly utilizes two ferrite pieces having extending fingers of closely similar dimensions that are joined in interleaving fashion and bonded to a ceramic substrate. The resultant assembly is sliced to provide closure sections for multi-track magnetic heads. Each closure section is joined to a ferrite wafer such that the wafer and closure section define a transducing gap therebetween.
