Abstract: The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface (MFS), a trailing shield at the MFS, and a MAMR stack disposed between the main pole and the trailing shield at the MFS. The MAMR stack includes a seed layer and at least one magnetic layer. The seed layer is fabricated from a thermally conductive material having electrical resistivity lower than that of the main pole. The seed layer has a stripe height greater than a stripe height of the at least one magnetic layer. With the extended seed layer, the bias current from the trailing shield to the main pole spreads further away from the MFS along the extended seed layer before flowing into the main pole, reducing temperature rise at or near the MAMR stack, leading to improved write head reliability.

Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a trailing shield, a main pole, an STO disposed between the trailing shield and the main pole, and a non-magnetic conductive structure (or non-magnetic conductive layers) adjacent to the main pole and in contact with the STO. The non-magnetic conductive structure provides additional paths for electrical currents to flow to the STO. The non-magnetic conductive structure enables higher current density to the STO without creating hot spots at the MFS. Maximum current efficiency and uniformity can be achieved with the non-magnetic conductive structure.

Abstract: Techniques for management of movable devices are disclosed. A system receives a request for an operation associated with a position on a rail. The system selects a component on the rail to execute the operation. The system identifies a rail segment that extends from the component's initial position to the position associated with the operation. The system requests a reservation of that rail segment. If the reservation is obtained, then the system applies electrical signals to move the component along the rails segment to the rail position associated with the operation. The system may also identify one or more other components, physical cells, etc. to reserve, in order to complete the operation.

Abstract: A spin torque reversal assisted magnetic recording (STRAMR) structure is disclosed wherein a spin torque oscillator (STO) is formed in the write gap (WG) and generates one or both of a radio frequency (RF) field on a magnetic bit to lower the required write field during a write process, and a spin torque on a field generation layer (FGL) in the STO that flips a FGL magnetization to a direction opposing the WG field thereby increasing reluctance in the WG and causing larger write field output from the main pole (MP). The FGL is between two spin preserving layers that each conduct spin polarized current from an adjoining spin polarization (SP) layer. Current is applied from the MP and trailing shield to the SP layers, and returns to a direct current source through a lead from the FGL. STO sidewalls are self-aligned to a MP tip upper portion.

The HDD may include a piezoelectric actuator locking mechanism integral to one of the bearing assemblies, such that actuation of the actuator either locks or unlocks the locking mechanism relative to a corresponding support post. When unlocked, the elevator platform assembly can be translated along the length of the disk stack via a motor.

Abstract: A bottom shield in a read head is modified by including a non-magnetic decoupling layer and second magnetic layer on a conventional first magnetic layer. The second magnetic layer has a magnetization that is not exchange coupled to the first magnetic layer, and a domain structure that is not directly affected by stray fields due to domain wall motion in the first magnetic layer. Accordingly, the modified bottom shield reduces shield related noise on the reader and will provide improved signal to noise (SNR) ratio and better reader stability. The second magnetic layer may be further stabilized with one or both of an antiferromagnetic coupling scheme, and insertion of an antiferromagnetic pinning layer. In dual readers, the modified bottom shield is used in either the bottom or top reader although in the latter, first magnetic layer thickness is reduced to maintain reader-to-reader spacing and acceptable bit error rate (BER).
