Abstract
A method of recording information on a media including a ferroelectric recording layer comprises writing the information by forming one or more domains within the ferroelectric recording layer, the one or more domains having a spontaneous polarization, and arranging the one or more domains in a pattern that improves a stability of the one or more domains.

A method of recording information on a media including a ferroelectric recording layer, the method comprising:
- writing the information by forming one or more domains within the ferroelectric recording layer, the one or more domains having a spontaneous polarization;
- and
- arranging the one or more domains in a pattern that improves a stability of the one or more domains.
A media for recording information in data storage device, the media comprising:
- a ferroelectric layer;
- and
- a plurality of domains formed within the ferroelectric layer, each of the plurality of domains having one of a first spontaneous polarization and a second spontaneous polarization;
- wherein the plurality of domains are arranged in a pattern having a proportion of first spontaneous polarization and second polarization that improves a stability of the plurality of domains.
A media for recording information in data storage device, the media comprising:
- a ferroelectric layer;
- and
- a background pattern disposed within the ferroelectric layer, the background pattern comprising a plurality of regions having one of a first spontaneous polarization and a second spontaneous polarization symmetrically positioned so that each region is adjacent to regions having opposite spontaneous polarization.
A method of recording information on a media including a ferroelectric recording layer, the method comprising:
- writing a background pattern to the ferroelectric recording layer, the background pattern comprising a plurality of regions having one of a first spontaneous polarization and a second spontaneous polarization symmetrically positioned so that each region is adjacent to regions having opposite spontaneous polarization;
- and
- writing the information by forming one or more domains within the ferroelectric recording layer so that the one or more domains straddle two or more regions of the background pattern, the one or more domains having a spontaneous polarization.
