摘要： A magnetic recording system configured for recording to a bit patterned media using both hypertrack recording and shingled recording. The magnetic recording system includes a write pole with a notched trailing edge that results in a write bubble with a trailing edge that has two outer convex lobes separated by a centrally disposed concave region. By locating one of the lobes over first and second data tracks of a hypertrack, a proper alignment of the relative phase of the two tracks can be maintained. Further adjustment to the alignment can be achieved by adjusting the radial location of the write head.

摘要： A method for making a bit-patterned media (BPM) magnetic recording disk by etching the recording layer using a patterned hard mask layer uses glancing angle deposition (GLAD) of additional hard mask material as a capping layer onto the tops of the patterned hard mask pillars while the disk is rotated about an axis orthogonal to the plane of the disk. In one embodiment the capping layer is deposited after the pillars have been only partially eroded during a partial ion-milling of the recording layer. Ion-milling is then again performed to remove the remaining recording layer material. In another embodiment, before ion-milling of the recording layer, the capping layer is deposited onto the tops of the un-eroded hard mask pillars. This increases the lateral dimension of the hard mask pillars so that after ion-milling of the recording layer, the magnetic islands have an increased lateral dimension.

摘要： A perpendicular magnetic recording (PMR) disk has a patterned template layer for the growth of the magnetic grains and the nonmagnetic material surrounding the grains. The template layer is a substantially planar platinum (Pt) or palladium (Pd) layer that is patterned to have Pt or Pd regions arranged in a hexagonal-close-packed (hcp) pattern with the Pt or Pd regions surrounded by Pt-oxide or Pd-oxide regions. The two separate regions of the template layer have different surface chemistries and energies, which provide a “chemical contrast” to impinging atoms during deposition of the metallic magnetic material and nonmagnetic (typically oxide) material, effectively guiding the deposition. The metallic magnetic material is preferentially deposited on the pristine, epitaxial Pt or Pd regions to form the magnetic grains, while the oxide migrates to the oxidized Pt or Pd regions due to the matching of lower surface energy.
摘要翻译：垂直磁记录（PMR）盘具有用于生长磁性颗粒和围绕晶粒的非磁性材料的图案化模板层。模板层是基本平坦的铂（Pt）或钯（Pd）层，其被图案化以具有以六方密堆积（hcp）图案排列的Pt或Pd区域，Pt或Pd区域被Pt氧化物包围或 Pd氧化物区域。模板层的两个分开的区域具有不同的表面化学和能量，这在金属磁性材料和非磁性（通常是氧化物）材料的沉积期间提供与入射原子的“化学对比”，从而有效地引导沉积。金属磁性材料优先沉积在原始的外延Pt或Pd区上以形成磁性颗粒，而氧化物由于较低的表面能的匹配而迁移到氧化的Pt或Pd区。

摘要： To provide enhanced operation of data storage devices and systems, various systems, apparatuses, methods, and software are provided herein. In a first example, a data storage device is provided that includes storage media comprising a shingled magnetic recording (SMR) storage region. The data storage device also includes a storage control system configured to receive write operations and responsively store write data in a first storage region prior to transferring into the SMR storage region. The storage control system is configured to determine a reporting pace for transferring the write operations from the first storage region into the SMR storage region, the reporting pace establishing a target performance that is tempered from storage of the write data into the first storage region. The storage control system is configured to report completion of the write operations over a host interface at the reporting pace.

摘要： A magnetic recording hard disk drive (HDD) includes, in addition to conventional servo sectors with position error signal (PES) blocks, data position error signal (DPES) blocks that are written into the data sectors when data is written in the data sectors of the data tracks. During readback the PES blocks from the servo sectors are decoded into PES values to allow the head to follow the servo track, while the DPES blocks are decoded to obtain DPES values that are used in the servo control loop to modify the head position so the head follows the center of the data track. In a shingled magnetic recording HDD, wherein the write head is at least two shingled data tracks wide, a DPES block is written in two radially adjacent data tracks when data is written into the data sectors of the shingled data tracks.

摘要： Embodiments of the present invention provide a simplified authentication transaction for reconnecting a storage device to a host apparatus that has completed authentication in the past. According to one embodiment, an authentication log is recorded in the host. Plural units of this log information are recorded in the storage device. At the time of transferring a content decryption key and usage rules between the host and the storage device, the decryption key and usage rules are recorded into the host as a log for the transfer. The used authentication log is recorded into the storage device as RAPDI. If RAPDI indicates the authentication log in the simplified authentication transaction, recovery transaction is permitted. The host device deletes/invalidates or holds the log for the transfer in accordance with non-permission/permission. In the case of permission, the key and usage rules are recovered by using a log for the transfer prior to the simplified authentication transaction.
