The present disclosure provides a signal conversion device including: a first converting section configured to convert a clock signal input through a first signal line, a data signal input through a second signal line, and a control signal input through a third signal line, into pulse signals including a first pulse train and a second pulse train; and a transmitting section configured to transmit the first pulse train through a fourth signal line and the second pulse train through a fifth signal line, wherein the control signal is a signal that, through a level transition, causes a control target device to switch between an active state and an inactive state, and wherein the first converting section is configured to put successive pulses into at least one of the first pulse train and the second pulse train in response to the level transition of the control signal.

A tape reader is provided that reads data from a tape without requiring specific alignment. The tape reader may include a reader head comprising a sensor array with a plurality of sensors that detect the data independent of the track within which the data is stored. Multiple sensors may detect data in each track instead of a single, dedicated sensor for each track. The sensor array may comprise multiple sensors in multiple dimensions, such as perpendicular to the movement of the tape or in parallel to the movement of the tape, including serpentine linear recording formats where the sensors may be in a matrix positioned at various angles from horizontal to vertical.

In one embodiment, a head for a storage drive includes a support member having a first media facing surface, and a wafer chiplet disposed on the support member and having a second media facing surface. In one embodiment, the lateral width of the chiplet is less than the lateral width of the support member and is less than the range of tape head and magnetic tape relative lateral motion. In one aspect of the present description, the chiplet has a third media facing surface which blends with first media facing surface of the support member, and the second media facing surface of the chiplet. In one embodiment, the chiplet is disposed on the support member so that a first bank of transducers of the tape head is centered on the support member and a second bank of transducers is offset from the center of the support member.

In an embodiment, a storage device includes a shingled magnetic recording device, a management unit, selection unit, and execution unit. The shingled magnetic recording device performs writing in unit of a band including tracks being adjacent to and partially overlapping with each other. The management unit manages management information mutually associating band identifier of the band, characteristic information indicating a possibility that data stored in the band is not referred to, and data identifier of the data in a case where the data is stored in the band. The selection unit selects the band of the shingled magnetic recording device storing the data based on the data and the characteristic information in a case where the shingled magnetic recording device is requested to store the data. The execution unit stores the data to the selected band.

A method and apparatus for increasing storage capacity on magnetic media. A dual-layer magnetic recording apparatus receives, a write operation instruction, bit position and bit value where the bit position includes a media surface position and magnetic media layer identifier. The dual-layer magnetic recording apparatus accesses a dual-layer magnetic media where the dual-layer magnetic media includes a first magnetic media layer with a thermally controllable coercivity, a second magnetic media layer and a separation layer. The magnetic layer identifier is determined to associated with be the first magnetic media layer or the second magnetic media layer. When the magnetic layer identifier is the second magnetic media layer, the bit value is written based on magnetically charging the second magnetic media layer and when the magnetic layer identifier is the first magnetic media layer the bit value is written based on heating and magnetically charging the first magnetic media layer.

A magnetic tape device includes a magnetic tape as a storage medium; a travel unit that moves the magnetic tape along a travel route; a magnetic head that is arranged at the travel route and performs data reading and writing for the magnetic tape that moves on the travel route; and a lifter unit that is arranged at the travel route and contacts the magnetic tape which is stopped on the travel route, where the lifter unit is able to reciprocate in a direction that intersects the travel route so as to separate the magnetic tape from the magnetic head.

A computer program product for positioning an actuator, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. The program instructions are executable by a processing circuit to cause the processing circuit to perform a method that includes generating or receiving, by the processing circuit, a first value representative of a lateral position of a tape, and using, by the processing circuit, the first value to adjust a position of a coarse actuator for moving a magnetic head in response to determining that the first value is in a first range relative to a first threshold. An integrator value is used by the processing circuit to adjust the position of the coarse actuator in response to determining that the first value is in a second range relative to the first threshold.

A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.
