Disk drive suspension assembly with PZT actuator having active and inactive regions

PendingCN121729735AArm with actuatorsRecord information storageMechanical engineeringPhysics
A suspension assembly includes a load beam terminating in a hinge, a gimbal assembly mounted to the load beam, and a base plate connected to the hinge and including an opening. A PZT actuator is disposed in the opening and includes opposing first and second ends. The PZT actuator includes an active region and an inactive region each extending between opposite first and second ends, a PZT material disposed in both the active region and the inactive region, and first and second electrodes, and an active region configured to cause active expansion and contraction of the PZT material in the active region in response to a voltage difference applied to the first electrode and the second electrode, and configured to not cause active expansion and contraction of the PZT material in the inactive region in response to a voltage difference applied to the first electrode and the second electrode of the PZT actuator.

Magnetic disk device

ActiveCN116778974BRecord information storageRecording head arrangementsDisks (device)Software engineering
Provided is a disk device capable of improving data format efficiency. The disk device includes a disk having a zoned servo area (ZBa) including a first region (RE1) having a first servo frequency, a second region (RE2) having a second servo frequency, and a third region (RE3) having the first servo frequency; a head; and a controller that demodulates first servo data of the first region, derives a position of the head, demodulates first correction data of the third region, and corrects the position of the head. The first region (RE1), the second region (RE2), and the third region (RE3) are arranged in order in a traveling direction (d2). The first region (RE1) and the second region (RE2) are adjacent to each other in a circumferential direction of the disk. The second region (RE2) and the third region (RE3) are adjacent to each other in the circumferential direction.

Magnetic disk device

ActiveCN116705081BManufacture head surfaceDisposition/mounting of recording headsIndustrial engineeringElectrical and Electronics engineering
The present disclosure provides a magnetic disk device capable of improving write performance. According to an embodiment, the magnetic disk device includes a magnetic disk, a head that writes data to a track of the magnetic disk, and a controller that performs positioning of the head, registers an address of a sector to which the data is written and a positioning error of the head at the address, judges whether or not a positioning error of a second sector that is two tracks ahead of a first sector to which the data is to be written is registered, sets a first threshold value that allows a write operation with respect to the positioning error of the first sector based on the positioning error of the second sector in a case where the positioning error of the second sector is registered, judges whether or not the positioning error of the first sector exceeds the first threshold value, and stops the write operation in a case where the positioning error of the first sector exceeds the first threshold value.
