From the background information supplied by the inventors, news correspondents obtained the following quote: "The present invention relates to data storage systems, and more particularly, this invention relates to magnetic heads and other structures.
"In magnetic storage systems, data is read from and written onto magnetic recording media utilizing magnetic transducers commonly. Data is written on the magnetic recording media by positioning a magnetic recording transducer over the media where the data is to be stored. The magnetic recording transducer generates a magnetic field, which encodes the data into the magnetic media. Data is read from the media by similarly positioning the magnetic read transducer and then sensing the magnetic field of the magnetic media. Read and write operations may be independently synchronized with the movement of the media to ensure that the data can be read from and written to the desired location on the media.
"An important and continuing goal in the data storage industry is that of increasing the density of data stored on a medium. For both disk and tape storage systems, that goal has led to increasing the track and linear bit density on the recording medium, and decreasing the thickness of the magnetic medium. However, the development of small footprint, higher performance tape drive systems has created various problems in the design of a tape head assembly for use in such systems.
"In a tape drive system, magnetic tape is moved over the surface of the tape head at high speed. Usually the tape head is designed to minimize the spacing between the head and the tape. The spacing between the magnetic head and the magnetic tape is crucial so that the recording gaps of the transducers, which are the source of the magnetic recording flux, are in near contact with the tape to effect writing sharp transitions, and so that the read element is in near contact with the tape to provide effective coupling of the magnetic field from the tape to the read element."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "A device according to one embodiment includes a substrate; and a plurality of thin films above the substrate, the thin films having at least one dielectric layer; wherein the at least one dielectric layer has a more crystalline structure towards a first end thereof than towards an end thereof opposite the first end.
"A magnetic head according to one embodiment includes a substrate; and a plurality of thin films above the substrate, the thin films having at least one transducer formed therein and at least one dielectric layer; wherein the at least one dielectric layer has a more crystalline structure towards a media facing end thereof than towards an end thereof opposite the media facing end.
"A device according to one embodiment includes a substrate; and a plurality of thin films above the substrate, the thin films having a dielectric layer of uniform composition; wherein the dielectric layer has a defined portion having a crystalline structure immediately adjacent an amorphous portion.
"Other aspects and embodiments of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention."
