Millipede - A MEMS-based Scanning-Probe Data-Storage
System
IEEE Transactions on
Magnetics, Vol. 39, No. 2, March 2003, pp. 938-945.
Abstract: Ultrahigh storage densities of up
to 1 Tb/in.2 or more can be achieved by using local-probe techniques to write, read back, and erase data
in very thin polymer films. The thermomechanical
scanning-probe-based data-storage concept called Millipede combines ultrahigh density, small form factor, and high data
rate. After illustrating the principles of operation of the Millipede, a channel model for the analysis of the readback process is
introduced, and analytical results are compared with experimental data. Furthermore, the arrangement of data-storage fields as
well as dedicated fields for servo and timing control is discussed, and system aspects related to the readback process, multiplexing,
synchronization, and position-error-signal generation for tracking are introduced. Finally, the application of (d; k) modulation coding
as a means to further increase areal density is presented, and the effect on the user data rates discussed.
