Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic film having uniform film thickness, minimal in drop out and excellent in electromagnetic conversion characteristic and corrosion resistance, by constituting a vessel for melting and evaporating materials by using a ceramic sintered compact having specific degree of sintering. SOLUTION: The degree of sintering of a vessel is >=80%. It is preferable that the vessel is constituted of a sintered compact having >=95% purity. It is preferable that the vessel is constituted of the sintered compact composed of MyO (where M means metallic element and y=0.6 to 1.1 is satisfied) and having >=80% degree of sintering and has 1-5 mm wall thickness. The inside of a vacuum tank 10 is evacuated, and a base material 3 is allowed to travel from a supply-side roll 2a along a cooling can roll 1 and coiled around a coiling- side roll 2b. A magnetic metal 6 in a crucible 5 is irradiated with an electron beam from an electron gun 7, and grains of the resultant evaporated magnetic metal 6 are vapor-deposited on the traveling base material 3. The overall thickness of the resultant magnetic film formed is 0.1-0.2 μm, and carbon, boron carbide, etc., are provided as a protective film. As the base material 3, a resin such as polyethylene terephthalate is used.

Abstract: PROBLEM TO BE SOLVED: To provide an instrument capable of exactly measuring the rigidity of the microregions of a thin type flexible tape in a state more approximate to an actual machine. SOLUTION: The instrument for measuring the rigidity of the microregions of the thin type flexible tape by using a projecting head 4 pressed to the tape has a tape supporting means 2 having a curved surface 7 for supporting the tape on its outer peripheral side in a state of applying tension in its longitudinal direction. The curved surface 7 of the tape supporting means 2 has an opening 11 for inserting a projecting head 4 from the inner peripheral side to the outer peripheral side in order to be pressed to the tape 10 supported at the curved surface 7 and further has a means for controlling the displacement quantity of the projecting head 4 and a means for measuring the reaction force from the tape 10. The rigidity of the microregions of the flexible tape is measured from the measured values of the displacement quantity 4 of the projecting head and the reaction force from the tape 10.

Abstract: PROBLEM TO BE SOLVED: To improve positioning accuracy of a magnetic tape in order to realize high storing density and large storing capacity by assuring close contact with a magnetic tape by pushing downward a friction sheet when a brake member which is provided to freely slide between one friction sheet and a half is slid in the direction for releasing the lock condition of the hub. SOLUTION: When a cassette tape is loaded in a drive, a lid 3 is opened by a ride opening/closing mechanism provided in the drive side. With this operation, a brake member 9 moves toward front end direction of the cassette body via projected area 15 of the end portion. Engagement of a braking pawl 11 for the tooth provided in the hub 6 is broken to release the lock condition of the hub. Thereby, the brake member 9 is placed in contact with a first projection 18 formed on a sheet clamping member 17 to push downward a friction sheet 8 in the direction of tape 5. The tape 5 is held by the upper and lower friction sheets 8, 7 and is then positioned.
