Abstract
The role of the scanning probes for digital storage has yet to be defined, but we can discuss some significant steps that have been taken in this field. We will describe the work on writing bits on magnetic media, although there are other strategies for storing data with scanning probes. Mamin2 has worked out a system where he creates small indents in PMMA for storing a single bit. Barrett3 has employed the probe to store and read bits as trapped charge in films of silicon nitride. At Canon, Takimoto4 has used the STM to store bits by changing the conductivity of the medium with a current pulse on the tip. Hosoka5 has used small gold clusters deposited by field desorption from the probe tip.

Measured via vibrating sample magnetometry; 3M Center, St. Paul, MN.
Measured via polar Kerr effect; Censtor Corp2, San Jose, CA. This technique averages the response of the surface layer over an area ~1 mm.
This is consistent with previous work (Ref. 6) which found a 15% variation in imaging sensitivity between tips.
