摘要：
The present invention relates to a domain expansion storage medium and processing method for processing a storage medium to obtain an improved readout performance. The magnetic properties of a storage layer (50) of the storage medium are altered by an ion beam projection lithography using a stencil mask to define magnetic domains and/or track patterns and/or servo patterns. Thereby, replication accuracy, speed and readout performance can be improved.
