pe Adaptive soft-output detector for magnetic tape read channels By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT In accordance with one embodiment, a computer program product includes a computer readable storage medium having computer readable program code that is readable and/or executable by a processor to: receive a signal including precoded data read from a magnetic tape medium and pass the signal through a soft detector to calculator first soft information about each bit of the signal and to provide adaptive compensation for the precoded data, send the first soft information to a soft decoder, pass the signal through the soft decoder to calculate second soft information about each bit the signal, and send the second soft information to the soft detector, wherein the precoded data is passed through at least one precoder prior to being written to the magnetic tape medium via a precoder that applies 1/(1⊕D2) to bits of data, where D is delay corresponding to bit duration Full Article
pe Head transducer with multiple resistance temperature sensors for head-medium spacing and contact detection By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A head transducer, configured to interact with a magnetic recording medium, includes a first sensor having a temperature coefficient of resistance (TCR) and configured to produce a first sensor signal, and a second sensor having a TCR and configured to produce a second sensor signal. One of the first and second sensors is situated at or near a close point of the head transducer in relation to the magnetic recording medium, and the other of the first and second sensors spaced away from the close point. Circuitry is configured to combine the first and second sensor signals and produce a combined sensor signal indicative of one or both of a change in head-medium spacing and head-medium contact. Each of the sensors may have a TCR with the same sign (positive or negative) or each sensor may have a TCR with a different sign. Full Article

pe Co-located gimbal-based dual stage actuation disk drive suspensions with offset motors By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Various embodiments concern a dual stage actuation suspension that comprises a loadbeam having a load point projection. The suspension further comprises a gimbal assembly having a point of contact that is in contact with the load point projection such that the gimbal assembly can gimbal about the load point projection. The gimbal assembly is cantilevered from the loadbeam and has an axis of rotation aligned with the load point projection and the point of contact. The suspension further comprises a pair of motors mounted on the gimbal assembly and positioned proximal of the point of contact. The pair of motors is mounted between a tongue and a pair of spring arms to rotate the tongue about the point of contact and the load point projection. The loadbeam further comprises a void into which the pair of motors extends. Full Article
pe Grooved tape guide roller By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A tape guide roller, for use with a tape drive that is configured to receive a length of tape, includes a roller body having an outer surface with one or more grooved areas and one or more non-grooved areas. The one or more grooved areas make up seventy-five percent or less of the outer surface, and the one or more non-grooved areas make up at least twenty-five percent of the outer surface. Furthermore, the one or more grooved areas are configured to affect traction between the roller body and the tape as the tape passes over the roller body. Full Article
