Patent ID: 7554896

Claim:
An apparatus comprising: a rotational drive unit for rotationally driving a disk substrate having a resist layer; an electron beam irradiation unit; a shift drive unit for shifting the irradiation position of the electron beam in a radial direction of said disk substrate; a first control unit for acquiring a rotational angle of said disk substrate from said rotational drive unit; a second control unit for acquiring a shift position from said shift drive unit; and a third control unit for forming a latent image corresponding to a predetermined pattern in said resist layer by controlling the irradiation position caused by said electron beam irradiation unit on said resist layer in accordance with said rotational angle of said disk substrate, said shift position and said predetermined pattern; wherein said electron beam irradiation unit includes a beam-adjusting system for adjusting the irradiation of said electron beam in such a manner as to spread over a plurality of tracks in the direction of traversing the tracks on said resist layer in response to the irradiation position control by said third control unit.
