Micro-electro-mechanical-system (MEMS)-based scanning-probe data storage devices are emerging as ultra-high-density, low-access-time, and low-power alternatives to conventional data storage. The probe-storage technique explored at IBM utilizes AFM probes and thermomechanical means to store and retrieve information in thin polymer films. High data rates are(More)
Ultrahigh storage densities of up to 1 Tbitiin’ have been 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, which we internally called “millipede”, combines ultrahigh density, small form factor, and high data rates through highly parallel(More)
Ultrahigh data storage densities on the order of 1 Tb/in<sup>2</sup> or higher can be achieved by using scanning-probe microscopy techniques to write, read back and erase data on very thin polymer films. The written information is usually read back in contact mode because it is simple to implement and analyze. However, the physical contact between the(More)
Ultrahigh storage densities of up to 1 Tb/in./sup 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, internally dubbed "millipede", combines ultrahigh density, small form factor, and high data rates. High data rates are(More)
Ultrahigh storage densities of up to 1 Tbit/in<sup>2</sup>. can be achieved by local-probe techniques to write, read back, and erase data in very thin polymer films. The thermo-mechanical scanning-probe-based data-storage concept called Millipede combines ultrahigh density, terabit capacity, small form factor, and high data rate. After illustrating the(More)
A scalable CMOS sensing architecture for highly parallel readback of signals from large two-dimensional local probe arrays for AFM(atomic force microscope)-based data storage is presented. The main challenge to the detection scheme comes from the fact that information signals are superimposed on carrier signals that are more than three orders of magnitude(More)
Integrated sensing and actuation are pivotal for making high-throughput scanning probe microscopy based devices where a large number of probes are employed for parallel operation. A thermoelectric sensor and an electrostatic-actuation platform fabricated on a cantilever can provide a simple way to integrate sensors and actuators on probes of these devices.(More)
