摘要： Magnetic sensors with effectively shaped side shields and their fabrication processes are provided. One such sensor includes a substrate, a sensor stack disposed on the substrate and having a stripe height, where the sensor stack further includes a front edge disposed at an air bearing surface (ABS) of the magnetic sensor, a back edge opposite of the front edge, and two side edges, and a side shield adjacent to each of the two side edges of the sensor stack, each side shield having a side shield height defined as a distance from the ABS to a back edge of the side shields, where the side shield height is greater than the stripe height, and where substantially no residue from materials used to form the side shield are disposed at the back edge of the sensor stack.

摘要： A transducing head may be connected to a controller and positioned proximal a data storage medium. The controller can be connected to a wear level identification circuit and configured to identify a first data region of the data storage medium having a first wear level and a second data region of the data storage medium having a second wear level. The first and second wear levels can respectively correspond to different amounts of component degradation of the data storage device.

摘要： A magnetic slider for magnetic data recording constructed by a process that allows for careful control of seed layer and overcoat thickness. The slider is treated by a process that result in surface pits and scratches. A refill layer is used to fill in the pits and scratches, the refill layer being constructed of a material that does not include Si or carbon. An angled ion beam etching can be used to remove portions of the refill layer that extend outside of the pits and scratches. Then, a seed layer comprising Si and a protective layer comprising C are deposited over the surface. Because the refill layer does not contain either of Si or C, the thickness of the seed layer and carbon overcoat can be accurately measured and controlled, without the refill layer being mistaken for seed or overcoat material.
摘要翻译：一种用于磁数据记录的磁性滑块，其通过允许仔细控制种子层和外涂层厚度的工艺构成。滑块通过导致表面凹坑和划痕的过程来处理。填充层用于填充凹坑和划痕，填充层由不包括Si或碳的材料构成。可以使用成角度的离子束蚀刻来去除在凹坑和划痕之外延伸的补充层的部分。然后，在表面上沉积包含Si和包含C的保护层的晶种层。因为补充层不含有Si或C中的任何一种，所以可以精确地测量和控制种子层和碳外涂层的厚度，而不会将填充层误认为种子或外涂层材料。

摘要： A head slider for supporting a head over a magnetic disk in a hard disk drive, and a method of making the head slider are disclosed. The tail section of the head slider has a deep write hole that may improve the altitude performance of the head slider by minimizing fly height variations at high altitudes (i.e., altitudes above 3000 m) or in low atmospheric pressure environments. The write hole prevents the fly height from changing. Additionally, the write hole limits the amount of lubricant that will flow over the ABS.
