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.
