    摘要： A storage device including many field emitters in close proximity to a storage medium, and a micromover, all in a partial vacuum. Each field emitter can generate an electron beam current. The storage medium has many storage areas on it, with each field emitter responsible for a number of storage areas. Also, each storage area can be in a number of different states to represent the information stored in that area. In storing information to the storage device, the power density of an electron beam current is increased to change the state of the storage area bombarded by the electron beam current. In reading information from the device, the power density of the electron beam current is reduced to generate a signal current from the storage area bombarded by the electron beam current. During reading, the power density is selected to be low enough so that no writing occurs. The magnitude of the signal current depends on the state of the storage area. The information stored in the storage area is read by measuring the magnitudes of the signal current. The micromover scans the storage medium with respect to the field emitters so that each field emitter can access many storage areas. The micromover causes a periodic change in the relative positions between the field emitters and the storage medium, thereby generating periodic field emitter trajectories.

    摘要： A data storage system that includes a positioning system for positioning the write/read mechanism and the storage medium of the data storage device with respect to each other in first and second predefined directions. The positioning system comprises a positioning apparatus comprising microfabricated first and second positioning assemblies. The positioning system further comprises a controller to position a positionable support structure of the first positioning assembly in a first predefined direction within a range of positioning that is larger than the range of movement of a moveable support structure of the first positioning assembly by controlling (A) a stationary support structure clamp in clamping and unclamping the positionable structure to and from the support structure, (B) a moveable structure clamp in clamping and unclamping the positionable support structure to and from the moveable support structure, and (C) the movement of the moveable support structure. In one embodiment, one of the write/read mechanism and the storage medium is carried by the positionable support structure so that it is positioned with the first positioning assembly. The other one of the write/read mechanism and the storage medium is positioned with the second positioning assembly. In another embodiment, the positionable support structure carries the second positioning assembly and one of the write/read mechanism and the storage medium is positioned with the second positioning assembly while the other is held stationary. In several embodiments, the read/write mechanism is used to mechanically write data to and electrically read data from the storage medium. In still another embodiment, the read/write mechanism is used to optically write data to and electrically read data from the storage medium. In yet another embodiment, the read/write mechanism is acoustically aided in electrically writing data to and reading data from the storage medium.

    摘要： A new form of rotating media disk drive is described. Data storage densities of many gigabits per square inch can be obtained at low cost. Data is stored in localized regions of electric charge that are stored within a thin dielectric layer that is coated upon both sides of an electrically conductive platter, rather than in magnetic domains that are stored in thin magnetizable films that are coated upon both sides of platters. Data is stored three-dimensionally, in electric dipoles whose axes are perpendicular to the plane of the platters, rather than in magnetic dipoles that lie along the surface of a platter. Data is read and written via ungated field emitter tips rather than with transformers and magnetically sensitive elements. The read/write head is built from the read/write head chip that contains field emitter tips and other elements. This chip is an active CMOS or other circuit whose active area is parallel to one side of a platter, rather than having a single, passive write element and a single, passive read element with external control circuits and amplifiers. The read/write head chip is formed in a silicon-on-insulator (SOI) wafer, with the tips and other microelectromechanical elements being formed in the top, silicon membrane, on isolated islands or pillars, and the supporting circuitry being formed in the base silicon wafer. Each read/write head chip is attached to the end of the arm of an actuator, in a manner similar to that used in magnetic disk drives. Individual, ungated field emitter tips are electrically isolated from one another and connected to, and intimately integrated with, analog and/or digital circuitry in the read/write head chip, rather than being electrically connected to many other tips and divorced from active circuitry in their immediate vicinity that controls them, as in flat panel displays. Multiple tips can be used to increase the data rate of the disk, and to provide spares to improve the reliability of the disk.

    摘要： A small form factor optical disk drive is provided that incorporates a SIL/objective lens assembly. A laser for the small form factor optical disk drive has a coherence function having maxima spaced apart by intervals. The optical disk drive is configured such that a roundtrip optical path through the SIL/objective lens assembly is such that a coherence value for the laser is located in one of the intervals.
