Embodiment Construction

[0027] Described below are the best embodiments currently contemplated for carrying out the invention. This description serves to illustrate the general principles of the invention and is not meant to limit the inventive concepts claimed herein. In addition, specific features described herein may be used in combination with other features described in each of the various possible combinations and permutations.

[0028] In the drawings, similar and equivalent elements are numbered the same throughout the different figures.

[0029] As described herein, the preferred embodiment of the present invention includes a magnetic recording head having a conductive thin film layer deposited directly on the wafer prior to the first magnetic shield insulator, referred to herein as the "conductive underlayer". In another embodiment, a thin insulating underlayer is formed between the conductive underlayer and the substrate.

[0030] A preferred wafer material for magnetic recording heads i...

Abstract

A magnetic head includes a wafer substrate and a conductive underlayer formed directly on the substrate. An insulating layer is formed on the conductive lower layer. Readers and / or writers or arrays thereof are formed on the insulating layer. Another magnetic head includes a substrate and an insulating underlayer formed on the substrate. A conductive underlayer is formed on the insulating underlayer. An insulating layer is formed on the conductive lower layer. At least one device is formed on the insulating layer, the at least one device is selected from a reader, a writer, and combinations thereof. A magnetic tape drive system and method for forming such a magnetic head are also presented.

Description

technical field [0001] The present invention relates to magnetic head structures, and more particularly, the present invention relates to magnetic head structures having a conductive underlayer deposited between the wafer and the nearest shield. Background technique [0002] Business, technology and entertainment applications rely on computers to process and record data. In these applications, large amounts of data are often stored or transferred to non-volatile storage media. Such storage media include magnetic disks, magnetic tape cassettes, compact disks, floppy disks or optical disks. Typically, magnetic tape is the most economical and convenient way to store or retrieve data. Continuously advance storage technology to increase storage capacity and storage reliability. For example, the storage density of data in the magnetic storage medium can be increased by improving the medium material, improving the error correction technology and reducing the unit bit size. For ...
