摘要： A burnishing head configured to provide extremely close control of the burnishing height, to aerodynamically eject particles generated by the burnishing process from beneath the burnishing head onto the disc surface, whence they can be swept from the disc by centripetal force, and to optimize the tribological relationship between the burnishing head and a disc being burnished. The burnishing head includes a plurality of burnishing pads arranged in an elliptical pattern, with the actual burnishing surface of the burnishing pads being either ion milled to provide a closely controlled surface texture, or lapped to a extremely smooth surface. The shape of the individual burnishing pads is also formed by the process of ion milling, and is either elliptical, or, preferably, an aerodynamic teardrop shape, which acts to aerodynamically displace generated particles from beneath the burnishing head. The burnishing surface of the burnishing pads is coated with a diamond-like coating to improve the tribological relationship between the burnishing head and the disc.

摘要： A burnishing head configured to provide extremely close control of the burnishing height, to minimize stiction between the burnishing head and a disc being burnished, and to optimize the tribological relationship between the burnishing head and a disc being burnished. The burnishing head includes one or more spacer pads, associated with selected ones of the burnishing pads on the burnishing head, which remain in contact with the surface of a disc being burnished. The height from the contact surface of the spacer pad to the contact surface of the burnishing pad determines the effective burnishing height. The burnishing head also includes moats, or recessed areas, surrounding the burnishing pads to minimize the stiction caused by generation of a liquid meniscus between the disc and contacting elements of the burnishing head, and which act as collection points for particulates generated by the burnishing process. The spacer pads preferably include microtextured contact surfaces to minimize stiction and wear and further include a diamond-like carbon coating to further improve wear characteristics.

The test head includes a MR stripe which has multiple taps which define multiple certification test MR stripe segments. Simultaneous connection of sensing logic to the multiple segments of the MR stripe allows for increased magnetic certification speed, and proper connection of sensing circuitry across appropriate taps on the MR stripe allows for testing for thermal asperities over a large portion of the disc surface. Various embodiments of the test head are disclosed.

摘要： A clock head assembly intended for vertical engagement to a disc in a disc drive for purposes of providing an arrangement of precise timing marks on the disc for use by a servo-writer. The clock head assembly includes a slider of the 50% or 30% size and a spacer adhesively attached to the upper surface thereof. In order to minimize stresses induced in the slider by the adhesive bonding, and to ensure that the clock head is capable of correct flying performance relative to the disc, the present invention envisions that the spacer surface bonded to the slider, or slider bonding surface, has dimensions substantially half the size of the dimensions of the surface of the slider to which the spacer is bonded. In another aspect of the invention, the spacer is designed to be suitable for large batch production. In another aspect of the invention, the spacer includes, adjacent the surface opposite the slider bonding surface, an overhanging rim portion, which acts not only as a readily optimized surface for bonding the spacer/slider assembly to the head suspension of the clock head assembly, but also as a visual aid to correctly orient the spacer relative to the slider during bonding of the two together.

摘要： A disc certification process, apparatus and article of manufacture for improved testing efficiency employs a testing head having a write element and a read element supported adjacent a rotating disc recording surface. The write element has a width that defines a "wide" write track width of at least N times the read track width defined by the width of the read element, wherein N is an integer greater than 1. The write element writes a signal onto the recording surface of the disc during a first disc rotation, to define a first annular write track having a "wide" first write track width in the radial direction of the disc. Then, during a second rotation, the read element reads the signal written in a first reading track width defined within the "wide" first write track. Thereafter, the read element is stepped to another read position adjacent the first write track and the read element reads the signal written onto the recording surface in a second reading track width defined within the first write track. If the write track width is more than two times the width of each read track, then the read element may be stepped to one or more additional read positions to read the signal written onto the recording surface in one or more further reading track widths defined within the first write track. In this manner, one relatively wide write track is formed with a write track width at least as great as two or more read tracks. The signals read by the read head during the reading steps are analyzed to determine the quality of the recording surface.
摘要翻译：用于提高测试效率的盘认证过程，设备和制品采用具有与旋转盘记录表面相邻支持的写入元件和读取元件的测试头。写入元件具有一个宽度，该宽度定义了由读取元件的宽度定义的至少N倍读取磁道宽度的“宽”写入磁道宽度，其中N是大于1的整数。写入元件将信号写入到在第一盘旋转期间记录盘的表面，以限定在盘的径向方向上具有“宽”第一写轨迹宽度的第一环形写轨道。然后，在第二旋转期间，读取单元读取以“宽”第一写入磁道中定义的第一读取磁道宽度写入的信号。此后，读取元件被步进到与第一写入磁道相邻的另一读取位置，并且读取元件读取在第一写入磁道内定义的第二读取磁道宽度中写入记录表面的信号。如果写入磁道宽度大于每个读取磁道的宽度的两倍，则读取元件可以被加到一个或多个附加读取位置，以读取在一个或多个进一步的读取磁道宽度内写入的信号，该读取磁道宽度在第一个写轨道。以这种方式，形成一个相对宽的写入磁道，其写入磁道宽度至少与两个或更多个读取磁道一样大。在读取步骤期间由读取头读取的信号被分析以确定记录表面的质量。
