Abstract: A storage apparatus comprises a storage medium (27) on which information can be stored in form of electronic charge. The storage medium (27) comprises a plurality of separated electrically conductive charge-storing elements (4) on its surface. The apparatus further comprises a read/write head (28) with which the information can be written to and/or read from the storage medium (27). Additionally, it contains driving means (29, 30, 31) which serves to move the read/write head (28) and the storage medium (27) relatively to each other. The read/write head (28) comprises cantilever means (2) with an electrically conductive read/write tip (1) which is connected to read/write means (24). For writing, a charge-, voltage or current source (33) that delivers the electronic charge is provided. For reading, measure means (36) which measures the electronic charge is provided.
