Because this was done on a magnetic medium, some is irrevocably lost, though not much.

The magnetic medium passes across a semi-fixed head which reads or writes data.

Degaussing' is the reference term used for the erasure of a magnetic medium.

This difference suggested that an isotropic magnetic medium would be desirable.

The technology is all about magnetic medium.

The basic idea is to control domain wall motion in a magnetic medium that is free of microstructure.

It is used for reliable retrieval of data recorded in the magnetic medium.

Next, here are the expressions for the various fields in a magnetic medium.

A multielement tunable magnetic medium was reported by Zhao et al.

This is made possible by moving the read/write head within the hard disk up a special ramp to prevent it from crashing against the magnetic medium.
