Abstract: The invention is directed to a non-rotating head used in linear scanning of linear magnetic tape. For example, the head may include a non-rotating contoured surface shaped to facilitate flyability of linear magnetic tape passing over the non-rotating contoured surface. A contact area defining a magnetic gap may protrude from the surface. The contact area that projects from the surface can contact the magnetic tape to read data from the tape and/or write data to the tape as the tape flies over the surface.

Abstract: A system and method to minimize the contribution of head channel spacing to the negative effects of transverse changes in dimensions of recording media having prerecorded servopositioning tracks. Multiple channels on the recording head are separated into multiple groups of head channels, and each group of heads is independently positioned relative to the pre-written servo tracks. The head comprises an actuator for each pair of head groups. The actuator adjusts the relative spacing between members of the pair in response to position error signals indicating misalignment between the heads and the pre-written servopositioning tracks on the medium.

Abstract: A magnetic tape recording system employing a single bump read-while-write head, methods of minimizing crossfeed signals between the read and write channels of magnetic tape recording systems, and electronic circuitry to implement such methods.

Abstract: A system is described including a data cartridge carrying a non-tape storage medium. The data cartridge includes read/write circuitry to access the non-tape storage medium and an external electrical connector coupled to the controller. The system further includes a tape drive emulator having an electrical socket to receive the electrical connector of the data cartridge. The socket may comprise a zero insertion force (ZIF) socket having a set of connectors that engage the electrical connections of the data cartridge. The tape drive emulator may mechanically actuate the ZIF socket upon sensing the insertion of the electrical interface of the data cartridge. Alternatively, the socket may include a mechanical actuation mechanism operable by a data cartridge library automation system to electrically couple the data cartridge to the emulation tape drive.

Abstract: A magnetic recording medium includes a highly permeable magnetic layer proximal to a recording layer. During recording, the permeable magnetic layer modifies the recording field from a recording head to produce consistently shaped recording transitions with a significant perpendicular component. The transitions are consistently shaped even though the distance between the recording head and the surface of the medium may change. Transitions so formed result in a reduction of noise from the medium surface roughness. The permeable magnetic layer further reduces noise caused by stray dipole fields.

Abstract: In one embodiment, the invention is directed toward a magneto-optic read head formed to suppress magnetic exchange coupling at regular intervals along a lateral direction of the read head. For example, in the region of the magneto-optic read head where light is reflected, i.e., the optical scanning region, the read head may be formed with a series of ferromagnetic exchange breaks that reduce lateral permeability of magnetic fields, and hence reduce lateral flux through the read head. In this manner, the effective resolution of the read head can be increased, thereby facilitating readout of data stored on narrower data tracks.

Abstract: A magnetic servo write head incorporates timing pattern read and write heads that are non-symmetrically slanted relative to an adjacent servo write head to improve timing pattern detection for a timing pattern written at an edge of a magnetic storage media. The slanted orientation of the timing write and read heads provides optimized timing pattern location and track width on a magnetic tape, while also allowing a sufficient number of windings to be used on an associated coil to improve overall signal-to-noise ratio.
