摘要： PROBLEM TO BE SOLVED: To suppress decrease in an output level due to a spacing loss, by preventing the adhesion of a clear stain (a silicon oxide film) to the tape sliding surface of a magnetic head.
SOLUTION: A protective film 16 composed of alkoxysilanes is formed on the tape sliding surface 10a of a magnetic head 10. The protective film, composed of the alkoxysilanes, is an inorganic film having no hydroxyl groups on the surface. Such a film, formed on the tape sliding surface of the magnetic head, decomposes due to the heat of tape sliding to obstruct the chemical bond between the active silanol and the tape sliding surface. As a result, the adhesion of the silicon oxide (clear stain) to the tape sliding surface, due to the low molecular siloxane existing widely in the environment, can be effectively prevented.

摘要： PROBLEM TO BE SOLVED: To provide a magnetoresistive head of which the reliability is improved by increasing the durability of the magnetic tape in the manner of suppressing the formation of protrusion around a magnetoresistive element to prevent defects such as spacing loss or tape damages, etc., and to provide the magnetic tape and a recording/reproducing system utilizing the magnetic tape.
SOLUTION: A thermal conductor member arranged being connected to the magnetoresistive element is formed of a material having a thermal conductivity higher than 20W/(m K), and the heat generated when the magnetoresistive element is used, is efficiently radiated to suppress the temperature around the magnetoresistive element. Also, by using a material having a melting point lower than the temperature at the use of magnetoresistive element for the material of a lubricant layer formed on a surface of the magnetic tape, the lubricant layer is not melted even though the head temperature rises when the magnetoresistive element is used.

摘要： PROBLEM TO BE SOLVED: To provide a tape cartridge provided with a sheet which has abrasion resistance and antistatic properties and never hinder viewing of the quantity of a tape.
SOLUTION: As the upper sheet 6 of a magnetic tape 4, the sheet is used in which a printed layer 6b printed in an abrasion resistant ink having the antistatic properties is provided on a transparent base material 6a. When a tape of high hardness such as an evaporated tape is used as the magnetic tape 4, the upper sheet 6 has a problem in durability. In the tape cartridge 1, which is provided with a window 2a for viewing the quantity of the magnetic tape 4 wound on hubs 5, the upper sheet 6 interposed between the window 2a and the magnetic tape 4 has to avoid hindering viewing. The printed layer 6b is formed in a pattern-shape, so that frictional force due to the reduction of the contacting area with the magnetic tape 4 is reduced and visibility is secured with light transmitted through gaps between the abrasion resistant ink.
