A method of writing to ferroelectric storage medium includes the steps of
applying a first write voltage to a ferroelectric layer for writing a
first bit in a first polarization direction and applying a second write
voltage to the ferroelectric layer for writing a second bit in a second
polarization direction opposing the first polarization direction. The
first write voltage having a first magnitude, and the second write
voltage having a second magnitude being greater than the first magnitude.
The ferroelectric layer having a ferroelectric imprint polarization
direction, and the first polarization direction being substantially the
same as the ferroelectric imprint polarization direction. The
ferroelectric medium contains first bits with a first surface area that
is substantially equal to second bits surface area. A probe storage
apparatus can use this method and ferroelectric medium.
