Title: Magnetic recording and reproducing device
Inventor: HIGASHIOUJI MASARU
IPC: G11B5/02
Filed: 1981-12-15
Abstract: PURPOSE:To improve wear resistance and saturated magnetic flux density by providing a lubricant film layer to the contacting surface between a magnetic tape and a head on the head side through the mechanochemical reaction of metallic elements in the magnetic tape. CONSTITUTION:A magnetic tape is brought into contact with the sliding surface of a head made of ''Sendust '' and the magnetic tape and head are put in relative motion. Consequently, iron elements contained in the magnetic tape as magnetic materials are stuck to the sliding surface of the head in an oxide film through mechanochemical reaction. In this case, the iron-oxygen ratio of the formed oxide film is Fe:O=1:(1.0-1.5) and its film thickness is about 200-300Angstrom . Further, its coefficient of friction is decreased to three-fifths as great as before the formation of the oxide film. The mechanochemical reaction is utilized, so the metallic oxide film never has >200-400Angstrom  and no evil influence is exerted upon recording and reproducing characteristcs.
