The invention relates to a flexure with varying thickness for a magnetic storage device. Examples of the present disclosure include a head gimbal assembly for a magnetic storage device. The head gimbal assembly includes a load beam, a read-write head, and an actuator configured to move the read-write head. The head gimbal assembly includes a flexure attached to the actuator. The flexure includes: an actuator side, the actuator side facing the actuator; and a recess formed in the actuator side and at least partially overlapping the actuator along a virtual plane that is substantially perpendicular to a length of the load beam.

To provide a magnetic recording head, a design method thereof, and a magnetic recording device that provide thermally activated protection against media damage during dynamic events such as operational shocks, load / unload processes, and emergency power-off.SOLUTION: A perpendicular magnetic recording (PMR) read / write transducer head for heat-assisted magnetic recording (HAMR) includes active nano bumper pads formed from thermally activated dynamic flying height (DFH) bulges that protrude closely on either side of the read / write element, and these bumper pads, which can be multiple, are arranged around the perimeter of he transducer head to absorb the heat generated by active heating element, including the write current. When this energy is absorbed, the bulges expand and change shape, protruding closely outward from the slider air bearing surface (ABS), protecting the read / write head from intentional and unintentional touchdowns.SELECTED DRAWING: None

A magnetic card reader including an electronic card, a magnetic reading head which is intended to read data contained in a magnetic strip of a magnetic card and to transmit these data to the electronic card, and a zone for passage of a magnetic card, in which a magnetic card is intended to slide and which includes a guide member intended to guide the magnetic card as it slides in the passage zone. The magnetic reading head is fixedly mounted on the magnetic card reader. The guide member is integral with resilient deformation members which are intended to come into contact with the magnetic card so as to deform it when the magnetic card slides in the passage zone in order to allow the magnetic strip to be read by the magnetic reading head.

Embodiments provide a magnetic disk drive and control method capable of preventing degradation of microactuator components. When adjusting the position of a magnetic head using a microactuator, the magnetic disk drive control unit applies a third voltage value based on the second voltage value to the microactuator when the absolute value of the first voltage value applied to the microactuator is corrected based on hysteresis and the absolute value of the second voltage value applied to the microactuator is positive. Furthermore, the control unit operates at least one of the voice coil motor and / or the microactuator other than the microactuator applying the third voltage value to adjust for any shortfall in adjustment by the microactuator.

The embodiment of the application discloses a magnetic tape storage system, a storage device and a magneto-electric disc. The magnetic tape storage system comprises a controller, a magnetic head driver, a magnetic head device and a plurality of magnetic tape wheels. The plurality of magnetic tape wheels are used for winding and unwinding the magnetic tape. The controller is used for predicting first disturbance information of the magnetic tape based on the rotating speed of a target magnetic tape wheel in the plurality of magnetic tape wheels, and controlling the magnetic head driver to drive the magnetic head device to move according to the first disturbance information. The first disturbance information is a displacement amount caused by the rotating speed of the target magnetic tape wheel. The actual relative position of the moved magnetic head device and the magnetic tape is determined, the first disturbance information is corrected based on the actual relative position, and second disturbance information is obtained. The magnetic head driver is controlled to drive the magnetic head device to move according to the second disturbance information. According to the embodiment of the application, the accuracy of data reading and writing can be improved.

Embodiments of the present invention provide a disk drive with high recording quality. In the disk drive of the embodiment, the processing circuit modulates the recording width in the radial direction of the first data sequence according to a first combination and a second combination when writing data to the first track. The first track is a track adjacent to a second track, which is a track on which data has already been written. The first combination is a combination of the first data sequence as data written to the first track and the second data sequence as data already written to the second track. The second combination is a combination of the polarities of the bit positions of the first track and the second track, which are adjacent to each other in the radial direction.
