摘要：
A photomagnetic memory medium of an amorphous thin film of a rare-earth transition metal alloy of non-columnar structure deposited on a substrate. In order to achieve the non-columnar structure, the alloy is sputtered in the presence of a plasma but the plasma is confined by a magnetic field so as not to touch the substrate. The alloy is preferably TbFeCo.
