摘要:
An information storage apparatus comprises a one or more storage media (168), which include a plurality of information tracks. Each storage medium (168) has a head assembly (170) having a substantially planar surface and a plurality of read/write heads positioned in registry with said information tracks. The read/write heads are arranged substantially in the plane of the planar surface. The information storage medium (168) and the head assembly (170) are arranged in mutually sliding abutment such that the read/write heads are substantially in sliding contact with the outer surface of the information storage medium in use. In another aspect an information storage and retrieval apparatus comprises an information storage medium (168) comprising an information storage area, and an array (170) of information read and/or write heads. The information storage medium (168) and array of heads (170) are arranged to be oscillated with respect to each other in use such that each region of the information storage area is aligned with at least one of the read/write heads during the oscillation.

A data storage assembly includes an array of fibers with magnetic coatings. The fibers are in an X-Y array, and individual fibers are selected by moving the array relative to fiber extracting and return assemblies. A selected fiber is pushed past a transducer for writing and/or reading data and then is returned to the array. A number of fibers equal to a data channel width, such as sixteen fibers, is accessed simultaneously in parallel. The array is made by winding a ring of fiber, making a honeycomb wall structure while winding the fiber, and then severing short segments from the ring.

A method of regulating the transverse position of a running magnetic tape (4) comprising steps of generating a unidirectional travelling-surface-wave by ultrasonic oscillation on a surface of an oscillator (62A,62B;65;66A,66B), and pressing the surface of the oscillator against a surface of the magnetic tape (4) so that the travelling direction (B,D) of the surface wave on the oscillator (62A,62B;65;66A,66B), has a component directed in transverse direction of the magnetic tape (4).

The invention concerns a voice correspondence object comprising a sound recording medium such as a magnetic tape (2), a read/write head (3), an electronic device (21, 25) connected to the read/write head for recording sound on the recording medium, a speaker (24), a driving mechanism (4, 5, 6) for the magnetic tape and a spring (7) for moving the driving mechanism when it has been wound, and a current generator (18) powering the electronic device and driving means (5, 6) for the generator driven by the spring when the latter is wound.
摘要:
A unidirectional traveling-surface-wave by ultrasonic oscillation is generated on a surface (20) of an oscillator (21), and a magnetic tape (4) is run in the direction opposite to the traveling direction of the surface wave by pressing the surface of the oscillator (20) against a surface of the magnetic tape (4).
