摘要： A method for forming a perpendicular magnetic recording head using an air-bearing surface damascene process and perpendicular magnetic recording head formed thereby is disclosed. The perpendicular head is formed by depositing a pseudo trailing shield layer over a pole layer and selectively etching the pseudo trailing shield layer to a depth equal to a desired trailing shield throat height. Then, a magnetic material is deposited in the resulting void.

摘要： An apparatus for providing data dependent detection in a data read channel is disclosed. Parameters in a read channel are dynamically adjusted according to data dependent noise. For example, a comparison in an add-compare-select (ACS) unit of a Viterbi decoder may be adjusted or offset terms in error event filters may be biased to choose a Viterbi sequence with more transitions or to compensate for polarity dependent noise.

摘要： A hermetic sealing approach involves welding an Aluminum cover onto a low-cost Aluminum housing. According to an example embodiment of the present invention, a metal housing having a base and sidewalls extending upward therefrom is adapted to receive and couple to an HDD arrangement. The metal housing is formed using material and processing (e.g., cold formed or die cast Aluminum) that are relatively inexpensive. A feedthrough arrangement including a plurality of communication pins extends through an opening in the base and is coupled thereto, with the communication pins adapted to pass signals between the inside and the outside of the metal housing. A metal cover is welded to an upper portion of the sidewalls and, with the feedthrough arrangement, hermetically seals the metal housing.

摘要： Techniques are provided for identifying the servo sectors in a track on a data storage device. A data storage device identifies the servo sectors in a track by reading distributed index bits from multiple servo sectors in a track. The data storage device analyzes only one index bit from each servo sector to identify the index of a track. In some embodiments, the index of a track can be identified after examining the index bits stored in a particular number of consecutive servo sectors, even in the presence of errors. The index bits in each track can have an error tolerance with a minimum Hamming distance greater than one. In other embodiments, a data storage device compares a sliding window of the index bits read from the servo sectors to all possible N-bit vectors that exist within a pattern of the index bits stored on a track.

摘要： Circuits and methods are provided for write through drivers in disk drive systems. A write through driver is a transceiver that includes a write driver circuit and a receiver circuit. The write driver drives a current signal to a write element through a first conductive interconnect. The write element writes data patterns to a magnetic hard disk in response to the current signal from the write driver circuit. The current signal returns to the receiver circuit through a second conductive interconnect. The return signal can be used for the diagnosis of write-safe conditions.

摘要： A slider fabrication assembly and method for making the same are provided. A slider is formed on a substrate. A corrodible component of the slider is exposed to an environment in contact with the slider. A kerf region of the substrate is positioned adjacent to the slider. The kerf region is removable from the slider. A sacrificial anode is embedded in the kerf region and exposed to the environment. The sacrificial anode is electrically coupled to the corrodible component of the slider thereby forming an electrochemical cell. The sacrificial anode is less noble, i.e., more corrodible, than the corrodible slider component, and thus corrodes first. When the kerf region is removed, the corroded sacrificial anode is removed as well.
摘要翻译：提供了一种滑块制造组件及其制造方法。滑块形成在基板上。滑块的可腐蚀部件暴露于与滑块接触的环境中。衬底的切口区域邻近滑块定位。切口区域可从滑块移除。牺牲阳极嵌入切口区域并暴露于环境中。牺牲阳极电耦合到滑块的可腐蚀部件，从而形成电化学电池。牺牲阳极比可腐蚀的滑块部件更不贵，即更可腐蚀，因此首先腐蚀。当切除切口区域时，腐蚀的牺牲阳极也被去除。
