    Abstract: A magnetic recording medium is formed with a laser textured glass or glass-ceramic substrate. The use of a pulsed, focused laser light beam, such as a CO2 derived laser light beam, enables the formation of an accurately textured landing zone on a glass or glass-ceramic substrate which is substantially replicated on subsequently applied layers.

    Abstract: A method and apparatus determining a data transducer head (26) position relative to a selected track (18) of plural concentric tracks within a magnetic disk drive (10). At least one prerecorded servo sector (20) within a data track includes four time staggered servo bursts (50). The first pair (70, 72) and second pair (74, 76) of servo bursts are radially offset from each other by generally a burst width such that an edge from each of the pair is substantially co-linear in forming a track null. The first pair (70, 72) is radially offset from the second pair (74, 76) by one-half of the burst width. The first pair (70, 72) is read to determine a first relative amplitude (100), and the second pair (74, 76) is read to determine a second relative amplitude (102). The radially offset, time staggered prerecorded servo bursts (50) can be of varying width and number to create the plurality of track nulls within a data track (18) about which the head (26) is positioned.

    Abstract: Two thrust bearing surfaces are separated by bearing fluid and are rotatable relative to one another. One of the bearing surfaces defines a plurality of continuous lands (122) extending from an inner (124) to an outer radius (126) of the bearing surface. Adjacent lands define between them a continuous groove (128) which has an undivided portion (130) in an inner annulus and a divided portion (132) in an outer annulus of the bearing surface. The continuous groove is divided in the divided portion (132) by an intermediate land (134) located between the adjacent continuous lands (122). The divided portion (132) of the continuous groove (128) communicates in unbroken fashion with the undivided portion (130).

    Abstract: A method to determine defective servo bursts written on a recording medium. Position data portions (10) include servo bursts (22) providing position error information retrieved by servo control system (2) having servo gate enabling signal (56). First likely defective burst is identified by reading each burst (22), measuring corresponding position error information and comparing to an acceptable range. While first likely burst retrieval is disabled, position error information from subsequent bursts is measured. If acceptable, the first likely burst becomes the first confirmed burst. If not, bursts before the first likely burst are selectively disabled and measured until a skipped burst is concluded as a first confirmed burst. While first confirmed burst retrieval is disabled, subsequent bursts are measured to find a second likely burst. By selectively disabling retrieval of a second likely burst and measuring, a second confirmed burst is determined. Then the first and second confirmed defective bursts are permanently marked.

    Abstract: A digital communication apparatus (20) transmits sectors of digital values that include error correction values used to detect and correct errors within the sector. Each sector consists of a number of blocks (70, 72, 74) and the error correction values of each block (70) are useful in correcting up to a maximum number of erroneous digital units (78, 84) in that block (70). The digital communication apparatus (20) encodes the blocks of digital units to transmit them through a channel (32) and then decodes the channel's representation of those encoded blocks, where the channel's representation occasionally contains burst errors. The encoding and decoding is performed in a manner that reduces the number of consecutive erroneous digital units caused by any one burst error to a number less than the number of blocks in a sector, ensuring that the error burst corrupts at most one digital unit in each block.

    Abstract: A transport drive system for use in a sputtering apparatus, particularly an in-line sputtering apparatus, is disclosed. The system transports a plurality of planar substrates and includes a plurality of transport beams (71) having a C-shaped cross section. Each transport beam has a first and second end, a first and second sides, a top surface, and a channel, disposed under the top portion, and forming a portion of the C-shaped cross section. The transport beam includes a substrate carrier (72) which secures the substrate or pallet (80) at the top portion of the substrate or pallet, and which is mounted in an alignment with an off-center relationship with respect to the center of the transport beam. In addition, the system for transporting includes a plurality of drive beams (50). Each drive beam includes a plurality of horizontally-oriented guide wheels (35) disposed on a top surface of the drive beam, the guide wheels engaging the channel of the transport beam. Each drive beam also includes a plurality of vertically-oriented wheel assemblies (40) disposed in a plurality of U-shaped cavities (52) in the drive beam. A motor is provided with each of the drive beams to drive the vertically-oriented wheel assemblies. A shield (60), provided below the drive beam, ensures that contamination does not reach the interior of the sputtering chamber.
