摘要： Disclosed is a grooving apparatus which can carry information on an information track at high recording density when carrying the information on the information track through a change in shape of a groove and which also can improve the signal-to-noise ratio of the information under reproduction. A grooving apparatus for forming a groove to function as an information track in an optical disk comprises an electron beam generator which emits an electron beam, an objective lens which focuses the emitted electron beam on the optical disk and which focuses the electron beam on a smaller range than the size of the groove, and an X-direction deflector and a Y-direction deflector which controls the electron beam so that the electron beam is focused in position on the optical disk, thereby forming the groove in the optical disk.

摘要： An electron beam projection apparatus including electron injection unit for irradiating an object with an electron beam. The electron injection unit includes a substrate, a cathode formed on the substrate for emitting the electrons, a control electrode formed on the substrate via an insulation layer in a manner enclosing the cathode for accelerating the electrons, and an anode formed on the control electrode via an insulation layer in a manner enclosing the cathode for converging the electron beam. The electron beam projection apparatus further including detecting unit formed on the anode via an insulation layer for detecting secondary electrons emitted from the object irradiated with the electron beam and differential pumping unit for producing a low vacuum condition in an space where the electron beam travels from the microscopic electron injection unit to the object. By maintaining a low vacuum condition, in the area where the electron beam is projected and detected, by using simple structural differential pumping unit, the detection accuracy can be achieved since the secondary electrons are amplified in the low vacuum area by the ionization of gas molecules.
