摘要： A data storage device configured to access a magnetic tape is disclosed, wherein the data storage device comprises at least one head configured to access the magnetic tape, wherein the head comprises a write element, a first read element substantially aligned with the write element, and a second read element laterally offset from the first read element. Data is written to a data track and read-after-write verify is performed using the write element and the first read element. In response to a read command received from a host, the data track is read using the second read element to compensate for a stretching of the magnetic tape.

摘要： 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.

摘要： The present invention generally relates to a method for forming a smooth gap of a damascene write pole. An opening having a side wall with a first angle with respect to vertical is formed in a fill layer, and a first non-magnetic layer is deposited into the opening by ion beam deposition. The ion beam is delivered to the side wall at a second angle with respect to vertical. The ratio of the first angle to the second angle ranges from about 250 to about 3.5.

摘要： A method of assembly a dual stage actuated suspension includes either applying an adhesive to a microactuator motor and then B-staging, it or applying an adhesive that has already been B-staged such as in film adhesive form, then assembling it to a microactuator and then finishing the adhesive cure. The method allows greater control over how much adhesive is used, and greater control over spread of that adhesive, than traditional liquid epoxy dispense methods. Additionally, a suspension is provided that has a wrap-around electrode such that both the driving voltage and the ground, which are normally connected at different sides of a PZT, can be connected at the same side of the PZT, thus simplifying electrical connections to the PZT.

摘要： A perpendicular write head having a wrap around shield and a conformal side gap. In fabricating the write head, the leading edge shield may be chemical mechanical polished down to a level that is substantially even with a chemical mechanical polishing stop layer. Because the leading edge shield and the chemical mechanical polishing stop layer are used as RIE stop for trench RIE, a fully conformal side shield may be formed with a LTE/LES.

摘要： Apparatus and related methods are described for adjusting servo gain. In an exemplary apparatus, a circuit determines a bias force error that occurs between an estimated bias force and an actual bias force on an actuator during movement by a servo motor.
