ABSTRACT:
A magnetic recording medium includes: a substrate; a recording layer that is formed on the substrate to have a grooved pattern; and a protection layer formed on the recording layer to fill in the grooved pattern, wherein the recording layer is defined to have a servo portion that retains servo data and a recording track portion that retains recording data, and wherein a first film thickness of the protection layer at the servo portion is larger than a second film thickness of the protection layer at the recording track portion by a thickness that is in a range from 1 nm to 10 nm.
