    摘要： The present invention provides a film forming apparatus and a film forming method realizing improvement in the degree of freedom in film formation while suppressing production cost. While conveying a base material by using a plurality of guide rolls, film formation is performed by atomic layer deposition by outputting precursor gases to the base material by a plurality of ALD heads. The ALD heads are disposed so as to individually face the guide rolls so that the precursor gases are locally output to the base material. The amount of the precursor gases used is reduced more than that in a related art, and the variety of kinds of the usable precursor gases is widened.

    摘要： Fine projections on a magnetic layer surface are controlled so as to reduce a media noise and improve C/Nmedia characteristic. A magnetic recording medium allows reproduction through a MR head or a GMR head. The magnetic layer on a main surface of a non-magnetic base has a coercive force of 80 KA/m or more and 180 KA/m or less. Assuming that a height of the fine projections is h and a diameter of the fine projections at a half-height h/2 is &phgr;h/2, 99% of the fine projections having a height not less than 10 nm satisfy a relationship as expressed by 100 nm≧&phgr;h/2≧40 nm.
