Abstract
Provided are devices and methods for reading data from rotating ferroelectric data storage media using a reader that includes a channel region disposed between a source and a drain. The data bits, stored as dipoles in the ferroelectric media, induce a current flowing through the channel region of the reader from the source to the drain when a bias voltage is applied to the media. The bias voltage can be tuned for desired reader operation, such as enhancing the signal or operating within a linear response regime.
