摘要:
A disk drive system includes a disk having a stiffening structure for improved vibration resistance. The stiffening structure is configured to improve stiffness and vibration resistance with respect to the (0,1), (0,2) and (1,1) vibration modes. The stiffening structure includes a rib-stiffening structure composed of a framework of interconnected ribs. The framework includes a plurality of concentric annular ribs and a plurality of radially spaced, radial ribs. One or more annular ribs are disposed at one or more locations along the radial dimension of the disk at which nodes of annular vibrations occur. Also, one or more radial ribs are disposed at one or more locations around annular dimension of the disk at which nodes of radial vibrations occur. The stiffening structure is disposed within a substrate layer of the disk during manufacture of the disk structure.

A magneto-optical head assembly that includes two load points. The two load points are laterally disposed from and longitudinally aligned with the center of the magneto-optical transducer carried on the head assembly. When contact between the head assembly and an asperity on the disc surface causes vibration of the head assembly in the pitch axis of the head assembly, the vibration is centered closely on the magneto-optical transducer, thus minimizing read/write signal modulation.

An optical disc storage system (10) includes an optical disc (12) having a data surface (70) and a transducing element (30) adjacent the data surface (70). An actuator (22) coupled to the transducing element (30) positions the transducing element (30) relative to the data surface (70). The system (10) includes a spindle motor (90) and a controller (34) coupled to the transducing element (30), the actuator (22) and the spindle motor (90) for reading and writing information on the data surface (70). A hub insert (72) is coupled to the optical disc (12) and has a stiffness which is greater than a stiffness of the optical disc (12). An attachment mechanism (94, 96, 98) couples the hub insert (72) to the spindle motor (90) and stress due to the attachment mechanism (94, 96, 98) remains substantially in the hub insert (72) to thereby limit stress applied to the optical disc (12) and the resultant distortion of the optical disc (12).
摘要:
A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system.

An abrasive article is provided. The article includes (a) a flexible backing having opposing first and second surfaces; (b) an abrasive layer comprising plurality of abrasive particles disposed on the first surface of the flexible backing; and (c) an adhesive layer comprising load bearing particles and an adhesive matrix, the adhesive layer disposed on the second surface of the polymer layer. At least a portion of the load bearing particles is substantially enveloped in the adhesive matrix and is in contact with the second surface of the polymer substrate.

摘要:
This invention relates to methods for plate dressing using slurry charged with abrasives and soft polymeric or metallic micro-nano spheres additives to produce substantially uniform abrasive height. Additionally, methods for plate dressing using slurry charged with abrasives and self-assembled polymers to produce substantially uniform abrasive height are disclosed.
摘要:
A method of making an abrasive article including the step of preparing a master plate with a surface having a shape. Depositing a spacer layer on the surface of the master plate. A slurry containing an adhesive and abrasive particles is deposited on a surface of the spacer layer. A substrate embedded with abrasive particles having a surface generally complementary to the surface of the master plate is fabricated. A spacer layer is formed by various method controlled the height of the protruded abrasive particles. The master plate and the spacer layer are separated from the substrate to expose abrasive particle protruding a substantially uniform height. An abrasive article made according to this method is also disclosed.
摘要:
The application discloses processes for fabricating a slider or head for a data storage device. The processes disclosed provide a transducer portion that is separated from a slider body by a gap. In an illustrated embodiment, actuator elements are fabricated in the gap to adjust a position of the transducer portion relative to the slider body.
