In making magnetic recording media by vapor-depositing magnetic metal film containing Co-Cr with 70-90 weight % Co as host material on a high polymer substrate, with or without intermediate layer(s) inbetween, making the high polymer substrate run around a cylindrical can, condition is selected such that linear expansion coefficient of the substrate is 1.0.times.10.sup.-5 -2.9.times.10.sup.-5 /.degree.C. and temperature of the can surface is 150.degree.-300.degree. C.; thereby normal or inverse curling of the resultant recording medium is substantially eliminated.

According to one embodiment, an lighting apparatus includes a base member, a light source configured to emit visible light, and a translucent cover including a translucent region which covers at least a front surface of the light source and emits the light emitted from the light source to the outside. The light source is provided on a front surface flat section of the base member, a luminous intensity of the light emitted from the light source has a directionality which is strong in a normal direction of the front surface flat section and becomes zero on a rear surface side. The translucent cover includes a domed shape having a maximum diameter at a position higher than a height of the position where the light source is arranged, and a transmittance of a region opposing the light source is 60% or less.
