Abstract
One-sided magnetic media for a hard disk drive. Methods are implemented to create a magnetic media with only one surface capable of recording data. The second surface is a non-data recording side of the media and is constructed so that it does not interfere with the recording properties of the recording side or the structural usefulness of the media. Additionally, the second surface can be a low quality surface capable of limited magnetic recording.
