摘要： Method and apparatus for testing and setting the field strength of permanent magnets in a magnetic bubble domain chip module, wherein the final molded module is formed to contain a pair of longitudinal slots which run through the module on opposite sides thereof. The module is inserted, via said slots, onto conducting members of a magnetic bubble module testing apparatus. The conducting members effectively provide one turn coils on each side of the module. Current is induced in these coils in such a way as to either add to or subtract from the bias field provided for the magnetic bubble domain chip by the permanent magnets of the module. The module is tested to determine the upper and lower operating levels of the bias field for effective operation of the chip, and the device is remagnetized to set the bias field of the module in the center, or optimal point, of the bias margin.

摘要： A bubble memory package is comprised of a nonmagnetizable heat sink formed with a pocket for receiving the field coil and magnetic chip carrier assemblies. The heat sink is massive and capable of dissipating the heat generated by a high density memory operating at a high frequency. The heat sink is not closed over the top of the coil and memory carrier assemblies to reduce eddy and circulating electrical currents formed in an electrically conductive heat sink. The heat sink is formed with a track guide for receiving a heat sink plate which may be of electrically nonconductive material but which has sufficient heat conductivity to assist in transferring heat into the heat sink. The top of the heat sink plate is formed with a pocket for receiving a permanent magnet to generate the bias field and the bottom of the heat sink is formed with a second pocket for receiving a magnet assembly. The entire package is surrounded by a magnetic shield container.

摘要： A field access magnetic bubble memory device including a memory chip applied with an in-plane magnetic field at need is disclosed. At a transient stop operation of the device before its interrupted state, an in-plane field is removed after it has been held for a predetermined period following the cessation of rotation thereof. The in-plane field may be increased upon the cessation of rotation thereof. At a transient start operation of the device after the interrupted state, an in-plane field having no rotation and the same direction as at the transient stop operation is applied for a predetermined period before the initiation of rotation thereof. The applied in-plane field may be increased upon the initiation of rotation thereof.

摘要： A device operating with the displacement of magnetic domain walls and comprising a layer of a magnetizable material having an easy axis of magnetization perpendicular to the plane of the layer, in which layer magnetic domain walls can be produced, maintained and moved, as well as a device to cause a magnetic propulsive field to act upon magnetic domains present in the layer so as to move them between previously determined positions. In order to obtain maximum speeds, the propulsive field acting upon a domain wall during the movement should at any instant have a value which is below the value for which a drop occurs in the function which characterizes the magnetizable material and which represents the relation between the propulsive field and the speed.

In a preferred arrangement the holding magnetic field is provided by tilting the magnetic field of the bias magnets off-normal.

摘要： A three-dimensional magnetic bubble device formed by depositing, on a flexible substrate, a plurality of pseudo-chips of amorphous metallic film capable of supporting magnetic bubbles. These pseudo-chips are interconnected by thin-film conductors also deposited on the flexible substrate. The substrate is then folded, on itself, a number of times to produce a three-dimensional magnetic bubble device. Optionally, a low temperature lamination step can be employed to complete the process. The folding step or steps, result in a number of layers, to which a common rotating magnetic field may be applied for propagation purposes.

摘要： A beam addressable file using as a storage medium an amorphous magnetic composition having uniaxial anisotropy. The storage medium can be prepared in thin film or bulk form or as particles in a binder. The storage medium can be comprised of a single element or a multicomponent system where at least one of the components has an unpaired spin so that the composition has a net magnetic moment. The storage comosition exists in a microcrystalline structure (i.e., it has localized atomic ordering over a distance 25-100 angstroms) and also in a substantially amorphous structure (i.e., when the composition has localized atomic ordering only over distances less than 25 angstroms). Binary and ternary compositions, either alloys or compounds, are suitable. particularly good examples are combinations of rare earth elements and transition metal elements. The magnetic properties of these amorphous magnetic compositions are easily changed during fabrication or after fabrication, and the compositions can be doped readily without adversely affecting magnetic properties. Either electron beams or light beams can be used to write information into the storage medium and optical readout is generally preferred. Curie point writing or compensation point writing is used.
