| abstract | PURPOSE: To obtain a good contact and excellent reproduced envelope by forming a fine particle coating layer containing a coarse particle layer on both ends or one end of the width of a tape on a polymer film and providing a ferromagnetic metal film thereon. n CONSTITUTION: The fine particle coating layer 6 consisting of the coarse particle layer 7 on which short wavelength recording by a rotary head is not performed and a protrusion layer 8 composed of water-base polymer is formed on the polymer film 5 in the vicinity of both ends or one end in a lateral direction. On the layer 6, the ferromagnetic metal film 9 consisting of Co-Ni or Co-Ti is formed by sputtering. Then a protective lubricating layer 10 consisting of a plasma polymerized film is provided on the film 9 to consititute the recording medium. The layer 7 removes deposites of dropout from the tape or contaminant in air from the step of an alloy composite head. Thereby, contact state of the tape is improved and an excellent reproduced envelope can be obtained. n COPYRIGHT: (C)1989,JPO&Japio |
