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.
Claims18
A method of manufacturing a tape head assembly comprising the steps of:
- providing a frame having a generally U-shaped form, the frame having a back portion extending in a longitudinal direction and two spaced-apart leg portions extending from the back portion in a substantially lateral direction;
- fixing a block to the frame, the block partially filling the space between the leg portions;
- fixing a cluster to the frame, the cluster partially filling the space between the leg portions, such that the block is interposed between the cluster and the back portion of the frame;
- and
- forming at least one longitudinal ridge which includes a portion of a surface of the frame.
A method of manufacturing a tape head assembly comprising the steps of:
- providing a frame bar having a back portion extending in a longitudinal direction and a plurality of spaced-apart leg portions each extending in a substantially lateral direction;
- fixing at least one block to the frame bar, the block partially filling a space between two respective ones of the plurality of leg portions;
- fixing at least one cluster to the frame bar, the cluster partially filling the space between the two respective ones of the plurality of leg portions, such that the at least one block is interposed between the at least one cluster and the back portion of the frame bar;
- and
- forming at least one longitudinal ridge which includes a portion of a surface of the frame bar.
