For example, the IBM Millipede probe-based mass-storage system uses a 32 x 32 array of probe tips, each placed on the end of a cantilever .
Other less-mature candidates for MEMS-based mass-storage systems include ferroelectric memories, charge-trapping devices, atomic motion in alloys (such as Pt atom migration), and charge motion within molecular media layers.
Designers of MEMS-based mass-storage systems need sufficient actuator force to accelerate the media sled, overcome spring force, and overcome external accelerations.
This system incorporates a wideband, precision 250 megasample/sec digitizer and mass-storage system with 134-megabyte (MB) capacity in a single package.
Control Data's test equipment mass-storage system (TEMSS) uses two environmentally sealed, removable 3.5-in.
