摘要:
A position control area (76A) is partly formed in the recording area (75) of a recording medium (70) and position information is recorded only in the position control area (76A). To record data in the recording medium (70) by a head (60) having a plurality of cantilevers (62A), (62B), ...., the position information is read by the cantilever (62E) corresponding to the position control area (76A) and, based on the position information, the positioning control or moving control of all the other cantilevers is performed.

In an information recording apparatus for recording information onto a recording medium by utilizing a technology in a near-field microscope, the information recording apparatus carries out recording with reliability and density. An optical probe (1) or micro-cantilever (12) utilized in a near-field microscope is used as a recording probe (26). The recording probe (26) at its tip is heated by laser light (28) illumination or heating by an electric heating element to radiate microscopic-region thermal energy through the tip to a recording medium (3). This makes it possible to record microscopically information onto the recording medium (3) that varies in physical properties due to heating. Furthermore, thermal energy is provided to a recording position through an auxiliary heat radiating means thereby enabling recording more positively.

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 (10) of probes (11) that in function faces the tape (2) 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 (20, 25, 40, 42) for moving the tape relative to the array of probes. The apparatus allows to store high data capacities at a small form factor.

There are provided a stable and highly sensitive nanometric mechanical oscillator having a considerably high detection resolution that enables detection of variation in force or mass on the nanometer order, as well as a method of fabricating the same, and a measurement apparatus using the same. A nanometric mechanical oscillator (10) includes a base (11), a tetrahedral oscillator mass (13); and an elastic neck portion (12) for connecting the base (11) and the tetrahedral oscillator mass (13). The oscillator (10) assumes a mushroom-like shape and has a nanometric size. The oscillator mass (13) assumes a tetrahedral shape and is suitable to be used as a probe of a scanning forth microscope in which the oscillator mass (13) serving as a probe is caused to approach to an arbitrary sample surface in order to observe the surface state.

A microfabricated microscope assembly (100) including a piezoelectric bimorph cantilever arm (102) mounted at one end to a first substrate (106). The free end of the cantilever arm has a tip (104) mounted thereto for scanning a scanned surface (110) mounted on a second substrate (114). The cantilever arm (102) and the substrate (112) are configured to carry out a predetermined write or read mode of operation, such as scanning tunneling microscopy or atomic force microscopy. The two substrates (106, 114) are spaced apart a fixed distance by spacer feet (120) which project from one of the substrates (106, 114) and which have their ends fixed to the surface of the other substrate by eutectic, anodic, or adhesive bonding. An array (100) of microfabricated microscope assemblies is formed using a plurality of individual assemblies (101). A number of different write/read modes of operation are accommodated, such as charge storage, molecular attachment, or magnetic domains.

A driving apparatus (100f) is provided with: a base portion (110); a stage portion (130) on which a driven object (12) is mounted and which can be displaced; an elastic portion (120) which connects the base portion and the stage portion and which has elasticity to displace the stage portion in one direction (Y axis); and a first applying device (161, 162, 22) for applying, to the elastic portion, an excitation force for displacing the stage portion such that the stage portion is resonated in the one direction at a resonance frequency determined by the stage portion and the elastic portion.

An information recording/reproducing device is provided with a recording medium (120) with a recording surface, a plurality of probes (135) that carry out at least either record processing or reproduction processing by scanning a plurality of information tracks (210) on the recording surface, a position detecting means that detects a position of at least one information track by using the probe for every plural divided regions into which the recording medium is divided in a direction intersecting the plural information tracks and which contain at least one information track, and a track control means that controls tracking of the probe used for at least either record processing or reproduction processing for every plural divided regions. Thus, the device structure can be simplified.
摘要:
In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice (19) wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator (21) which moves a recording medium (13) in the X direction is set higher than the lowest resonance frequency of an actuator (24) which moves the recording medium (13) in the Y direction. At the time of recording or reading information, the recording medium (13) is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator (21).
