ABSTRACT:
An integrated read/write head structure saves and retrieves saved data stored in storage locations on a ferroelectric optical storage medium. A first ultra-violet light source generates a single beam for exciting the electrons of a ferroelectric molecule of the optical storage medium. An induced electric field transducer orients the potential difference of the ferroelectric molecule during saving data. A second ultra-violet light source generates a single beam and a MOSFET transistor detects the electric fields from a ferroelectric molecule.
