    摘要： The present invention provides a method for manufacturing optical disk substrates whereby grooves and pits of optical disk substrates are formed highly accurately and finely, so that resulting optical disks can be of large-capacity and reduced in noise level. A coat of an organic material is provided on a substrate which is to be a master, on which a mask material is patterned as an etching mask. After the coat of the organic material is etched, the mask material is removed, whereby a master is obtained. A metallic coat is formed to the master. A metallic main body portion is integrally formed on the metallic coat. A metallic portion comprising the metallic coat and metallic main body portion is separated from the master. A metallic stamper is thus formed.

    摘要： Pits are exposed and formed on a resist master disc by an electron beam recorder. A leading end and a trailing end of each pit are substantially the same form. The electron beam recorder includes: an electron beam source that discharges electron beams; a voltage controller that generates voltages based on a predetermined information signals; control electrodes that deflect the electron beams based on the voltages; a shield plate having a passing position to pass the electron beams and a shielding position to shield the electron beams; and a turntable that carries and rotates the disc. The voltage controller controls the voltages applied to the control electrodes to substantially equalize a first velocity of the electron beams to travel from a first shielding position to the passing position with a second velocity of the electron beams to travel from the passing position to a second shielding position.

    摘要： An optical recording medium is disclosed. The optical recording medium includes an optical disk substrate. A control layer is formed on the optical disk substrate. The control layer includes a control track provided with a tracking control signal. A photosensitive material is formed on the control layer capable of forming a recording track as a result of a change in an optical property of the photosensitive material that is responsive to a specific light beam radiation. The optical property of all the recording tracks on a predetermined circumference of the optical disk substrate is entirely changed in advance.
