“…A solution providing a substantial increase in data rate is obtained by employing MEMS-based arrays of probes that operate in parallel, with each probe performing write/read operations on an individual storage field. One implementation of a probe-based storage device where this concept was first applied and which is known in the scientific community as the "millipede" prototype developed by IBM, is presented in [12], [13], and [214], see Fig. 23.…”

Abstract-The recording performance of data-storage devices, in which write/read elements move relative to a storage medium to reliably store and retrieve information, depends on the capability of servo mechanisms to provide the necessary positioning accuracy. The desired characteristics of servo mechanisms for datastorage systems include robustness against variations of environmental parameters, high resolution, accuracy, stability, and fast response. This paper presents a comprehensive overview of advanced servo-control methods for data storage. The applications are to well-established recording technologies, including magnetic tape and magnetic disk systems as well as CD/DVD/Blue-Ray optical data-storage systems. Moreover, newer holographic and nearfield optical systems and the emerging probe-storage technology are also addressed. Emphasis is given to the potential exhibited by the technologies considered for achieving ultra-high storage capacity, as required by the exploding demand in data-storage capacity for archival systems and massive multimedia data storage.Index Terms-Control systems, hard-disk drive, holographic data storage, optical-disk drive, scanning-probe data storage, servomechanism, tape drive.

“…It has been used in lithography [48], [49], in nanomanipulation [50]- [53], and in nanoassembly [2], [54], [55]. Another interesting application is the "millipede" project at IBM Research [56], [57]. This device consists of an array of cantilevers, operated in parallel (see Figure 6) and has the potential to achieve data storage densities of 1 Tb/in 2 .…”

Abstract-The Atomic Force Microscope (AFM) is one of the most versatile tools in nanotechnology. For control engineers this instrument is particularly interesting, since its ability to image the surface of a sample is entirely dependent upon the use of a feedback loop. This paper will present a tutorial on the control of AFMs. We take the reader on a walk around the control loop and discuss each of the individual technology components. The major imaging modes are described from a controls perspective and recent advances geared at increasing the performance of these microscopes are highlighted.

“…There is a lot of ongoing research on storing information by altering the electric properties of ferroelectric materials [7], changing the state of phase-change materials [8], or using the traditional magnetic techniques with probes [9]. One of the most promising approaches is the thermomechanical formation of indentations in thin polymer films [10]. With probe-based techniques, storage densities of over 1 Tb/in have been demonstrated.…”

We present a new data allocation method for probe-based storage devices that use multiple, simultaneously accessed parallel data fields. Our method uses blocks of data of unequal length for allocating a sector in the various storage fields. The amount of data stored in each field depends on the sector's offset from the beginning of the allocation round and on the storage field used. Numerical results demonstrate the storage efficiency improvement that is achieved by the proposed method. We show that this method can be applied to atomic force microscopy-based probe storage devices.
