ABSTRACT:
In magnetic disk structure having a high density, positioning errors (generally referred to as "flutter error") occur due to fluctuation (i.e., flutter) of a magnetic disk. As a result reading precision deteriorates. This is a significant problem in realizing a large capacity providing magnetic disk apparatus. This can be resolved by magnetic apparatus such that a suspension which holds a slider having a magnetic head at one end and which is attached to a supporting arm at the other end is inclined so that an interval between the suspension and the magnetic disk is small on the inner rim side and is large on the outer rim side with this arrangement the occurrence of the positioning error due to the fluctuation of a deformation of the magnetic disk is reduced, thereby enabling a high density recording of the magnetic disk.
