Abstract: A storage device and a method for scanning a storage medium. A storage medium for storing data in the form of marks is scanned by an array of probes for mark detecting purposes in a scanning mode. The storage medium has fields with each field to be scanned by an associated one of the probes. At least one of the fields has marks representing operational data for operating the scanning mode. Scanning parameters are computed from the operational data and the scanning mode is adjusted according to the computed parameters.

Abstract: Read/write components for AFM-based data storage devices are provided. In particular embodiments, a read/write component (30, 45, 50, 65, 80) comprises lever means (31, 51, 66, 82) and a support structure (32, 52, 67, 81), the lever means being connected to the support structure for substantially pivotal movement. The lever means (31, 51, 66, 82) provides first and second current paths between a pair of electrical supply lines (R, C) on the support structure via which the lever means can be connected in use to power supply means operable in a write mode and a read mode. A write-mode heater (36, 47, 56, 73) is provided on the lever means in the first current path, and a read/write tip (37, 57, 74, 84) is provided on the write-mode heater. A read-mode heater (39, 46, 58, 75, 83) is provided on the lever means in the second current path. Decoupling means (38a, 38b, 40a, 40b, 60, 61, 77a, 77b, 78a, 78b) is arranged to inhibit current flow to the write-mode heater via the first current path in use when the power supply means is operated in the read mode. The component, with separate write and read-mode heaters, can thus be addressed in both the write and read modes via a single pair of supply lines. Other embodiments provide read/write components (100) employing a thermal decoupling mechanism, and read/write components (80) where read-sensing is performed by a proximity sensing arrangement between the lever means and the support structure. Sensing apparatus (115) for atomic force microscopes is also provided where tip movement can be detected via similar proximity sensing arrangements.

Abstract: Described is a method for erasing data recorded in a data storage device in which a data bit is written onto a surface by applying a first combination of energy and force to the surface via a tip to form a pit in the surface representative of the data bit by local deformation of the surface. The method comprises applying a second combination of energy and force via the tip to prerecorded deformations of the surface to be erased to substantially level the surface.

Abstract: This die-shaped coarse-approach positioning device is particularly suited forthe sample holder of a scanning tunneling microscope or the like. It comprises two blocks (21, 23), one (21) stationary, the other tiltable with respect to thestationary one. The blocks (21, 23) are connected on one side by a spring-like sheet metal (20). The tiltable block (23) can be moved, and with it the sample (33), by turning a screw (28) which presses down onto an elastic pad (30). The tilting of the tiltable block (23) occurs against the effect of the sheet metal (20) until the block (23) touches down onto a wedge (39) insertable in the gap (24) between the blocks (21, 23), and consisting of an elastic material, however having a spring constant much higher than the effective spring constant of the sheet metal (20). In the application shown, the sample can be lowered onto a tunnel tip (343 attached to a fine-approach positioning device (35).

Abstract: A transducer for detecting movement of an article mounted for movement in a plane, the transducer comprising: a heater facing the plane of movement of the article and having a temperature dependent resistance; and, an edge defined in the article between regions of different thermal conductivity; wherein, as the article describes the movement, the edge moves relative to the heater producing a corresponding variation in heat loss from the heater and a corresponding variation in resistance of the heater.

Abstract: In accordance with the present invention, there is provided an apparatus comprising a tape having an information layer on which information is storable in the form of perturbations, an array of probes that in function faces the tape such that the probes scan the surface of the tape, means for selectively forming the perturbations via the probes, means for detecting the presence of the perturbations via the probes, and drive means for moving the tape relative to the array of probes. The apparatus allows to store high data capacities at a small form factor.
