  • Embedded lapping guide for a magnetic head cluster
    Patent number: 6950289
    Abstract: A magnetic head cluster is provided along with a method of making a magnetic head cluster. The magnetic head cluster comprises a substrate having a plurality of magnetoresistive (MR) read and inductive magnetic write transducers and a plurality of terminals formed thereon. A plurality of lapping guides are also provided on the substrate between adjacent transducers.
    Type: Grant
    Filed: March 14, 2002
    Date of Patent: September 27, 2005

  • Thin film magnetic tape head and method of manufacturing therefor
    Patent number: 6849148
    Abstract: A magnetic tape head assembly is provided along with a method of manufacturing a magnetic tape head. The magnetic tape head comprises a cluster of thin film inductive or magnetoresistive read/write elements, an I-block preferably made of a ceramic material, a U-bar also preferably made of a ceramic material, and a base preferably made of a ceramic or metal material. The U-bar has a substantially U-shaped form providing a recess into which the I-block and the cluster are fixed. A bottom surface of the U-bar, I-block, and cluster is fixed to the base to form a slider assembly. A top surface of the U-bar, I-block, and cluster is machined or etched to form one or more tape bearing surfaces thereon.
