A system is provided to receive a first request to write data to an HDD which comprises a plurality of platters with corresponding heads, wherein a respective platter includes a plurality of tracks. The system aligns the heads at a same first position on a first track of each platter, and distributes the data as a plurality of data sectors to track sectors located at the same first position on the first track of each platter. The system then receives a second request to read the data from the HDD, and aligns the heads at a same random position on the first track of each platter. Subsequently, the system reads, during a single rotation of the platters, all data stored on the first track of each platter, stores the read data in a data buffer, and reshuffles the read data in the data buffer to obtain the requested data.

A method of assembly a dual stage actuated suspension includes either applying an adhesive to a microactuator motor and then B-staging the adhesive, or applying an adhesive that has already been B-staged such as in film adhesive form to the microactuator then assembling the microactuator into a suspension and then finishing the adhesive cure. The adhesive can be applied to bulk piezoelectric material, with the adhesive being B-staged either before or after it is applied to the bulk piezoelectric material, and the piezoelectric material then singulated into a number of individual piezoelectric microactuators. The method allows greater control over how much adhesive is used, and greater control over spread of that adhesive and control over potential contamination, than traditional liquid epoxy dispense methods.

Provided is a magnetic recording medium processing device including a loading slot into which a magnetic recording medium, a medium movement path extending from the loading slot, a first magnetic head arranged in the medium movement path and detecting a magnetic signal from the magnetic recording medium, a magnetic information reproducer reproducing the magnetic information, based on a signal of a specific frequency included in analog signals output from the first magnetic head, an interfering magnetic field generator generating an interfering magnetic field along the medium movement path, and an interfering magnetic field controller controlling the interfering magnetic field generator to generate a first interfering magnetic field until the first magnetic head starts detecting the magnetic signal, and controlling the interfering magnetic field generator to generate a second interfering magnetic field different in frequency spectrum from the first interfering magnetic field while the first magnetic head detects the magnetic signal.

A tape drive allows for an increased track density by partially overlapping adjacent tracks as each successive track is written. Each successive track overwrites a portion of the width of the previous track, thereby reducing the width of the previous track. This process can be applied repeatedly thereby producing an arrangement of shingled data tracks across the width of the tape. In an embodiment, single-pass verification of data written in this manner is accomplished using a head assembly with two read heads per track. A first read head positioned behind the write head verifies that the data written is correct, and a second read head positioned over the previous track verifies that data on the previous track remains intact after being partially overwritten.

A data storage device can have one or more timestamps to indicate chronological information associated with data stored in the data storage device. A controller may be connected to a timestamp module and a transducing head to allow a timestamp to be written to a magnetic data storage medium as directed by the timestamp module. The timestamp can consist of chronological information relating to user-generated data stored on the data storage medium.

A first reader spans first and second tracks of a recording medium and provides a first signal responsive to a first total longitudinal field of the first and second tracks. A second read spans two other tracks, at least one of the two other tracks being different from the first and second tracks. The second reader provides a second signal responsive to a second total longitudinal field of the two other tracks. A third reader spans two or more of the tracks and provides a third signal responsive to a total perpendicular field of the two or more tracks. User data is decoded from the first, second, and third signals.

A data storage device is disclosed comprising a voice coil motor (VCM) configured to actuate a head over a disk. The head is used to read data recorded on the disk to generate a read signal, and the read signal is processed to generate a current command signal at a servo sample rate having a servo sample interval. A current flowing through the VCM is detected, and a current error signal is generated based on a difference between the current command signal and the detected current flowing through the VCM. An analog command signal is generated based on the current error signal, and the analog command signal is applied to the VCM. A saturation in the analog command signal is detected, and a first deglitch window is generated during which the saturation detection is disabled, wherein the first deglitch window is programmed relative to the servo sample interval.

A turntable device, comprising: a spindle and two arms. The two arms may comprise: a housing; one or more buttons; a spindle engagement portion; a stylus cartridge; a power supply; one or more wireless communication devices; a linear actuator; a motor; and a vertical solenoid. The spindle may receive a phonographic record, and the spindle engagement portion may engage with the spindle, such that the arms are entirely supported via said spindle and only the spindle.
