    Abstract: A method for a producing multichannel magnetic head comprises the steps of disposing core elements, each having such a shape that the core has been cut along the gap surface, in such a manner that each of the same number of the gap forming surfaces as the number of the required channels are placed on the same plane, fixing each of the core elements on core holders so that the relative position between each of the core elements will not be changed so as to constitute a first core element assembly, constituting a second core element assembly having the same construction, maintaining said first and second core element assemblies with a predetermined relative position, and inserting a shield plate after the gap between each of the cores has been filled with a binder.

    Abstract: A magnetic read-record head is built on a transducer frame and a return core frame. The transducer frame is made by machining an assembly of two concentric cylindrical members to produce a frame with a central locator bar. Each transducer has a magnetic core with a notch in it and a coil wound around a portion of the core. The core notch fits over the locator bar to align all the transducers in the transducer frame. The return core frame receives magnetic cores in the form of U-shaped clips. After the clips are fastened to the return core frame, the curved portion of the U is removed leaving two rows of return cores. Then the return frame, with the cores, is attached to two transducer frames full of transducers to make a completed multichannel readrecord head.

    Abstract: A magnetic head assembly and the method of manufacture therefor is disclosed which includes a housing having long and short body portions and a magnetic transducer comprising first and second core portions that are clamped in the respective body portions. The body portions are made of a nonmagnetic elastic material and include core-gripping surfaces defined by aligned slots cut through respective mating surfaces of the body portions. Prior to assembly, the body portions are permanently deformed by applying forces that exceed the elastic limit of the body material whereby the core-gripping surfaces are spaced apart by a distance less than the thickness of the core portions. Thereafter, the coregripping surfaces are forced apart to receive the respective core portions. When the forces are released, the core-gripping surfaces spring back to tightly clamp the core in the slots.

    Abstract: A read-after-write magnetic head with closely spaced, parallel read and write gaps is disclosed. A magnetic circuit comprising a pair of core pieces is provided for each gap. A coil is mounted on the outer core piece of each pair and each outer core piece is held in a core piece holder which extends over substantially all of the outer core piece except for a core piece tip in order to reduce flux leakage between circuits. Both of the inner core pieces for each gap are held in place by a center core piece holder of unitary construction. Two shields are located within the center core piece holder and are shaped to cooperate with the magnetic head housing to complete flux paths surrounding each of the read and write portions of the head.

    Abstract: A recording head mounting arrangement is provided for precisely positioning a plurality of recording heads in a housing adjacent a face of a magnetic memory disk. Each recording head is mounted on an individual assembly for individual removal if desired. Holes for mounting the head assemblies are provided in the housing in precise positions and means are provided for keying the assemblies to the housing for maintaining head orientation. Each individual assembly comprises a circular body extending through the housing with the head mounted on a conventional gimbal spring inside the housing. A pneumatic actuator is concentric with the circular body for advancing and retracting the head. Means are provided for passing electrical leads from the recording head to the outside of the housing.
