摘要:
A light beam (L) from a light source (12) is divided into two beams (Lr, Lt) by a polarized beam splitter (16). The beam (Lr) is reflected by a mirror (20), is converted into a P-polarized beam by a 1/4 λ plate (18), passes through the beam splitter (16), is reflected by prisms (22, 24), passes through a polarized beam splitter (26), is reflected by a mirror (30), is converted into an S-polarized beam by a 1/4 λ plate (28), is reflected by the beam splitter (26), and is finally incident on a detector (34). The beam (Lt) is converted into an S-polarized beam by a 1/2 λ plate (36), is reflected by a polarized beam splitter (38), is reflected by the upper face of a cantilever (44) supporting a probe (46), passes through a polarized beam splitter (52), is reflected twice in a prism (54), passes through the beam splitter (38), is reflected again by the cantilever (44), is converted into an S-polarized beam by a 1/4 λ plate (40), is reflected by the beam splitter (52), is converted into a P-polarized beam by a 1/2 λ plate (56), passes through the beam splitter (26), and is finally incident on the detector (34). The detector (34) outputs the displacement of the cantilever (44) from the optical path difference of the beams Lr and Lt.
摘要:
A data storage apparatus includes a first lever body (10) having a piezoelectric driving section, and a second lever body (20) which is disposed to separate from and to be perpendicular to the first lever body (10), and has a piezoelectric driving section. A recording medium (22) is formed on a portion of the second lever body (20), and records desired data. A plurality of probes (12₁ to 12 n ) are disposed on a portion of the first lever body (10) to oppose the recording medium (22) at a predetermined interval, and detect a change in state at predetermined positions on the recording medium (22) as a change in tunnel current or a change in three-dimensional pattern. A voltage applying circuit (39, 40) alternately applies predetermined voltages to the piezoelectric driving sections of the first and second lever bodies (10, 20) to separately drive the plurality of probes (12₁ to 12 n ) in different directions, thereby three-dimensionally scanning the recording medium (22).

A memory device comprises a base plate (10) with a memory element supporting layer (14), a probe (18) with a pointed tip portion, and a fine scan element (20) for causing the probe (18) to scan over the surface of the memory element supporting supporting layer (14). When the probe (18) is approached to the surface of the memory element supporting layer (14) and a suitable bias voltage is applied across the probe (18) and the memory element supporting layer (14), a tunnel current is cause to flow therebetween and a specific region of the surface of the supporting layer (14) is excited. The excited region can adsorb a memory element (16), such as one molecule di-(2-ethylhexyl) phthalate. By causing the memory element (16) to be adsorbed selectively on the memory element supporting layer (14), data is recorded in the form of a projection-and-recess pattern. The recorded data can be read out by observing the surface configuration of the supporting layer (14) in accordance with the principle of an STM (scanning tunneling microscope).

As a first one of electronic circuits including an atomic prob, a micro STM arithmetic circuit device is provided. The micro STM arithmetic circuit device comprises an information-rewritable micro STM recording medium (10; 34; 58; 68) and a micro STM recording apparatus which temporarily stores information on the recording medium such that the information can be read as a variation in a tunnel current. The recording apparatus has a probe (probes) (12; 36, 38, 40, 42, 44; 54, 56; 70) for writing/reading information on the recording medium and a scanner (72) for varying a position relation between the probe and the recording medium. As a second application of the electronic circuits, a micro STM recording apparatus is provided. The micro STM recording apparatus uses a recording medium having a specific format as the micro STM recording medium (86; 98; 102; 106; 110; 126) in which recorded information is read as a variation in a tunnel current. That is, the recording medium has an address area (92) in which address information is recorded and a data area (94) in which data information is recorded.
