Magnetic storage device and manufacturing method thereof

摘要

A magnetic storage device and a manufacturing method thereof, the magnetic storage device having grooves formed on a substrate, each of the grooves having a magnetic film formed therein. Since the magnetic head does not contact directly with the magnetic film, reliability of the magnetic disk increases. Moreover, the reproduced output of the magnetic head increases since the space between the magnetic head and the magnetic disk can be reduced. Accordingly, high-density recording becomes possible.
