Abstract:
An apparatus comprises mechanically scanned ferroelectric data storage media. A scanning electrode contacts the scannable surface with a contact force. The ferroelectric data storage media generates a piezoelectric potential that is picked up by the electrode. The piezoelectric potential has a polarity that varies as a function of data polarity on the data storage media.
