Abstract:
A magnetic disk comprising:a substrate;recording track sections made of a magnetic member for recording and reproducing information magnetically, said recording track sections being provided on said substrate; anda guard band member provided between said recording track sections adjacent to each other so that they are substantially continued in a track direction, said guard band member being harder than said magnetic member and being made of a non-magnetic material;wherein one of:said magnetic member is not provided in a lower area of said guard band member having a thickness substantially equal to a thickness of the magnetic member forming said recording track sections, whereby magnetic anisotropy is applied to the track direction, and a fluctuation in a reproduced signal in the recording track sections becomes small andanother magnetic member with a different thickness from said magnetic member forming said recording track sections is provided in a lower area of said guard band member having a thickness substantially less than the thickness of the magnetic member forming said recording track sections, for adjusting magnetic anisotropy of the recording track sections: andthe disk surface formed by said magnetic member forming said recording track sections and said guard band member has a flat surface, whereby an antifriction protective layer is not needed on the recording track sections.
