ABSTRACT:
A fine pattern having first elements within track widths and second elements, which are shifted half a track pitch from the first elements, are drawn across the entire surface of a disk accurately and at high speed. A transfer pattern for a magnetic transfer master carrier is drawn by scanning an electron beam on a disk coated with resist. The first elements and the second elements, which are shifted half a track pitch such that they straddle adjacent tracks, are drawn. While the disk is rotated unidirectionally, the electron beam is deflected in the radial direction within a single track of the disk to draw the first elements. Deflection of the electron beam in the radial direction is shifted half a track, to draw the second elements that straddle adjacent tracks at the same time.
