A circuit having a stationary portion and a rotating portion suitable for an arcuate scan assembly in a storage device is disclosed. The circuit includes a stationary encoder outputting an encoded write signal; a power supply; and a rotary transformer comprising a stator and a rotor. The stator has at least one stator winding and the rotor has at least one rotor winding, with the stationary encoder coupled to the stator winding. A decoder is provided and includes an input coupled to said at least one rotor winding and rotating with the rotor. The input receives an encoded write signal, and the decoder further has an output. Also provided is an amplifier coupled to receive the decoder output, and further being coupled to the power supply via the rotating transformer. The amplifier rotates with the decoder and the rotor. Also, at least one read/write head is included and is coupled to receive an amplifier output from the amplifier and return a read data signal to the amplifier. Also disclosed is a method for reading and writing data to a tape storage medium. The method may include the steps of: providing a rotating head drum adjacent to the tape, the head drum including at least one read/write head and an amplifier coupled to the head; encoding preamplifier control signals and the data in a synchronous signal; transmitting the synchronous signal through a rotating transformer to the head drum; transmitting a clock signal through the rotating transformer; transmitting a power to the preamplifier; and decoding the synchronous signal so that the preamplifier is directed to write the data to the tape.

Arcuate scan read/write assembly

A method and a system for recording and reading magnetic information on a linear tape are disclosed. A write head is disclosed that is wider than the read head. Tracks of discrete, elongate bits of information, which are oriented perpendicular to the long axis of the tape, are recorded by the write head. The read head avoids crosstalk without employing azimuth recording techniques by re-positioning the read head over the center of the narrowed track prior to beginning the reading process. The combination of the narrow read head and re-positioning of the read head enables track trimming, which provides high lateral track density. The drive disclosed is capable of reading and recording on existing QIC tapes, as well as higher density cartridges.

Track trimming and orthogonal recording for cartridge tape

A transformer comprising a rotor and a stator. The rotor is positioned for rotation about a rotational axis and having a plurality of windings. At least one of said plurality of windings is positioned at a first radial distance from the rotational axis, and at least another of said plurality of windings is positioned at a second radial distance from the rotational axis. The stator has at least two windings, a first of said at least two stator windings being provided at said first radial distance, and at least a second of said windings being provided at said second radial distance from said rotational axis. Alternating ones of said plurality of rotor windings inductively couple to alternating ones of said at least two stator windings as said rotor rotates about said axis.
