Abstract: Systems and methods for storing and reading data in a data storage system are provided. The data storage system includes a storage medium for storing data. The storage medium stores data as a plurality of topographical features. Further, the data storage system includes one or more transducer. One or more transducer writes data on the storage medium. Additionally, the data storage medium includes one or more gates. A first voltage bias is applied to one or more gates. The data storage system further includes, one or more read heads. One or more read heads include one or more Floating Gate Transistors (FGTs). The first voltage bias creates an electric field between one or more FGTs and one or more gates. A change in the electric field is detected by one or more FGTs.
