Abstract: A fabric separable fastener member is provided which comprises a fiber for a base fabric and a fiber for a fastening element firmly anchored by the fused fiber for the base fabric and which is excellent in flexibility and durability without a back-coated layer. The separable fastener member comprises (?1) a ground warp, (?2) a ground weft containing a binder fiber, and (?3) a pile yarn, and the pile yarn (?3) is anchored by the fused binder fiber. In the separable fastener member, each of the ground warp (?1), the ground weft (?2) and the pile yarn (?3) comprises a polyester fiber, the mass ratio of the ground warp (a1) relative to the ground weft (a2) is 40/60 to 80/20, and the mass ratio of the total amount of the ground warp (a1) and the ground weft (a2) relative to the pile yarn (a3) is 90/10 to 50/50.

Abstract: A ferromagnetic thin film comprising Fe as a main component, at least one element of B, C, Al and Si and at least one transition metal element except noble metals Au, Ag, Ru, Pd, Os, Ir and Pt. This can accomplish a ferromagnetic thin film having a high saturation flux density, a high initial permeability and a low coercive force, and also having an excellent corrosion resistance and thermal resistance. The ferromagnetic thin film having the above high performances can be manufactured in a high yield by forming the above materials into a film in an atmosphere of a mixed gas of Ar and N.sub.2, and thereafter heating the film at a given temperature. It is possible to give a magnetic head suitable for high-density recording, that enables good recording and reproducing on and from a magnetic recording medium having a high coercive force.

Abstract: A magnetic disk medium having a magnetic layer formed on its substrate, is characterized in that in a portion of the substrate where a magnetic head runs is formed a concave groove in which a cushion material is provided, whereby the contact pressure appearing between it and the magnetic head is lowered.Preferably, the cushion material is either plastic foam selected from the group consisting of polyurethane foam, polystyrene foam, cellular polyethylene, cellular rubber, cellular polyvinyl chloride, and foamed polyester, or elastic silicone resin.
