Embodiment Construction

[0033] combined reference figure 1 with 2 , an example of a locally detected data storage device includes a two-dimensional array of cantilever sensors 10 disposed on a silicon substrate 90 . Row conductors 30 and column conductors 40 are also provided on the substrate. Each sensor 10 is addressed by a different combination of row 30 and column 40 conductors. There is a pair of column conductors 40 associated with each column of sensors 10 and one row conductor associated with each row of sensors 10 . Each sensor 10 comprises a silicon cantilever structure with a length of around 70 microns and a micron thickness. The ends of the cantilever legs are fixed to the substrate 90 . The apex of the cantilever has a degree of freedom of movement in a direction perpendicular to the substrate 90 . The cantilever apex carries a resistive heating element and a silicon tip facing away from the substrate 90 . The legs of the cantilever are highly doped to provide a conductive path. ...

Abstract

The invention discloses an apparatus for reducing the sensitivity of an article to mechanical vibration, the apparatus comprising: a frame; (300) mounted in the frame for bidirectional movement relative to the frame along a first axis of displacement First (m1) and second planar masses; a first lever (330) that can rotate around a first fulcrum (360) fixed to the frame, one end of the lever is connected with the first mass (m1) and the other end is connected with the first mass (m1) A second mass (m2) is connected, and the fulcrum (360) is disposed between the end points of the lever, wherein in response to a mechanical vibration applied to the frame along the displacement axis, the torque acting around the fulcrum through the first mass is determined by the The torque acting about the fulcrum of the second mass cancels out, so that the product used, carried by the first mass, has a reduced sensitivity to vibrations.

Description

technical field [0001] The present invention relates generally to a device for reducing the sensitivity of an article to mechanical vibrations, and in particular to a device for reducing the sensitivity of a local probe storage device to mechanical vibrations. Background technique [0002] P. Vettiger et al. published a local detection in "The "Millipede"-More than one thousand tips for future AFM data storage" published in IBM Journal of Research and Development, Vol.44 No.3, March 2000 Examples of storage devices. A millipede device includes an array of thermal resistance sensor probes. The array can be used for detection of surface topography in applications such as surface visualization and data storage. In data storage applications, the data recorded in the surface topography can be read out by moving the thermal resistance sensor over the surface and detecting the change in the thermal conductivity between the sensor and the surface as the distance between the sensor...
