摘要： Described herein is a system that includes a sled and a data storage device positioned within the sled. The sled includes a base, an electrical connector positioned within and movable relative to the base, and a locking mechanism. The locking mechanism is positioned within the base and movable, relative to the base and the electrical connector, between a locked position and a unlocked position. In the locked position, the locking mechanism restricts movement of the electrical connector in at least one degree of freedom relative to the base. In the unlocked position, the locking mechanism does not restrict movement of the electrical connector in the at least one degree of freedom relative to the base. The data storage device is co-movably coupled to the electrical connector.

摘要： A low permeability electrical feed-through involves a laminated structure having a conductor layer sandwiched between adjacent insulator layers, which are sandwiched between adjacent diffusion control layers, where the laminated structure provides a relatively narrow and long, high aspect ratio diffusion channel to inhibit the leakage of gas from within a sealed device to the external environment. The electrical feed-through may comprise lower and upper electrical connection pads that are positioned within different regions of the feed-through but still electrically connected by way of a first via positioned in a sealed region, the conductor layer, and a second via positioned in an external environment region.

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： A two-dimensional magnetic recording (TDMR) disk drive has a disk with servo tracks with a track pitch that varies across the radius of the disk. The servo track pitch (STP) is related to the cross-track spacing (CTS) of the multiple read sensors in the TDMR head structure. The CTS is given by the equation: CTS=(CTO)cos θ+(ATO)sin θ, where θ is the skew angle, and CTO is the cross-track spacing and ATO the along-the-track spacing of the read sensors at zero skew angle. The optimal variable STP profile results in track misregistration reduction because it allows each read sensor to read a different servo half-track and thus noise sources not correlated to noise sources read by the other read sensors. The servo tracks may be arranged into a plurality of annular bands, with the STP in each band being fixed and different from the STP in the other bands.
摘要翻译： 二维磁记录（TDMR）磁盘驱动器具有磁盘，其具有在磁盘半径上变化的磁道间距的伺服磁道。 伺服磁道间距（STP）与TDMR磁头结构中的多个读取传感器的交叉磁道间隔（CTS）有关。 CTS由下式给出：CTS =（CTO）cos＆Thetas; +（ATO）sin＆thetas;其中＆thetas; 是倾斜角度，CTO是零倾斜角度下读取传感器的轨道间距和ATO沿轨道间距。 最佳可变STP曲线导致轨道配准减小，因为它允许每个读取传感器读取不同的伺服半轨迹，并因此读取与其它读取传感器读取的噪声源不相关的噪声源。 伺服磁道可以被布置成多个环带，其中每个频带中的STP是固定的，并且与其它频带中的STP不同。

摘要： Embodiments of the invention include data storage system with a servo system with a VGA feedback loop that corrects gain errors for servo bursts arising from track phase misalignment and difference in frequencies between AGC and servo bursts for seamed and seamless servo patterns. After the servo fields have been written as part of the manufacturing process, in one embodiment measurements of phase misalignment are made and recorded in nonvolatile memory for use during normal operation of the drive. One embodiment includes measuring misalignment using relative signal magnitudes from test bursts with various linear densities written in a data area during the self-servo writing process. In an alternative embodiment the measurements of phase misalignment can be made real-time during normal operation of the drive.
