  • Patent number: 7164557
    Abstract: An air bearing burnish slider burnishes very small asperities and cleans the loose particles that adhere to the magnetic recording media. The slider applies a controllable contact force to effectively burnish disk asperities or partially attached particles. In addition, the slider cleans the loose particles effectively while flying in a stable fashion. In a low pitch design, diagonal rails push particles away from the disk surface and trailing edge pads contact the disk at lower linear velocities. Rail pads retain loose contamination and debris in their pockets and burnish asperities. Another design provides a milder burnish force and flies in a high pitch configuration. The trailing edge pads provide stable contacts and the rails help in sweeping away debris. In both designs, the contact forces can be controlled by adjusting linear velocities. A step taper at the leading edge provides a pitch-producing lift force.

  • Patent number: 6379570
    Abstract: A method is provided for making a well-defined, highly-predictable chevron type MR sensor for a read head. A first material is selected for a first gap layer. A selected second material is deposited on the first gap layer followed by a resist frame that has elongated openings exposing elongated top portions of the first gap layer that extend at an acute angle to a head surface of the read head. A selected reactive ion etch (RIE) is employed to etch away the exposed portions of the second material layer down to the first material of the first gap layer. The material of the second material layer is chosen to be etched by the RIE while the material of the first gap layer is chosen not to be etched by the RIE. An example is Al2O3 for the first gap layer, SiO2 for the second material layer and a RIE that is fluorine based. The resist frame is removed leaving elongated strips of the second material layer extending at the aforementioned angle to the head surface.

  • Patent number: 6131271
    Abstract: A method planarizes a first pole piece layer of a write head by lapping without delaminating the first pole piece layer from an underlying second read gap layer on a wafer substrate. This is accomplished by separating or dicing the first pole piece material layer in a field region about rows and columns of first pole piece layers of magnetic head assemblies so as to reduce the stress of the first pole piece material layer in the field. Accordingly, when the wafer substrate is lapped, such as by chemical mechanical polishing (CMP), a reduced stress prevents the first pole piece material layer from delaminating from the second read gap layer during the lapping operation.

  • Patent number: 5251806
    Abstract: The present invention relates generally to a new interconnection and a method for making the same, and more particularly, to an elongated solder interconnection and a method for making the same. On an electronic carrier, a pad is formed on which a solder mass is deposited and capped with a metal layer, thereby forming an elongated solder interconnection. A further elongated solder interconnection can now be formed by forming a second solder mass on the first solder mass that has been capped by a metal layer. Additional elongated solder interconnection can be formed by capping the preceding solder mass and/or the last solder mass with a metal capping layer. Alternatively, the encapsulating layer can be in the form of a sidewall spacer formed on the sidewalls of the solder mass.

  • Patent number: 4359042
    Abstract: An insulating contoured solar window is provided for use with an enclosed chamber or structure such as an evacuated flat plate solar collector. The solar window is supported about its peripheral portion and in order to withstand the pressures exerted thereon by atmosphere the window may be outwardly domed along its longitudinal and/or transverse extent. Intermediate portions between domes are supported by a lower portion of the structure. A perforated or segmented absorber may be located in the chamber and spaced from the peripheral and intermediate portions in order to prevent heat loss from the absorber to the structure through the window. A pair of such solar windows may be arranged with corresponding peripheral and intermediate supports in opposed supporting contact.
