20100208573 | METHOD AND DEVICE FOR DETECTING FERROELECTRIC POLARIZATION - An information storage device comprises a media including a ferroelectric layer and a conductive layer and a cantilever adapted to be actuated toward the media. A tip extends from the cantilever and an electrode associated with the cantilever. When the cantilever is actuated, the tip applies a contact force to strain the media so that a charge is coupled from the ferroelectric layer to the tip. A signal is applied to the electrode to generate electrostatic force between the electrode and the conductive layer, causing the cantilever to vibrate based on a frequency of the signal. Vibration of the cantilever causes the contact force applied by the tip to the media to vary. Polarization of the ferroelectric layer can be determined based on one or both of a baseband signal generated by the charge accumulated at the tip and an upper-band signal generated by the variation in phase of the charge accumulated at the tip. | 08-19-2010 |
