Abstract:
1. An electron beam lithography method, for drawing elements that constitute a transfer pattern of a magnetic transfer master carrier, by scanning an electron beam on a disk having resist coated thereon, placed on a rotatable stage which is also movable in the radial direction, while rotating the rotatable stage; the transfer pattern comprising: first elements, which are arranged within track widths of circumferential tracks within transfer regions at each sector thereof; and second elements, which are arranged shifted a half track width from the tracks, to straddle two adjacent tracks; the electron beam lithography method comprising the steps of: unidirectionally rotating the disk; deflecting the electron beam in the radial direction within a single track of the disk; and scanning the electron beam so as to fill in the shapes of the first elements of the track to draw the first elements, simultaneously deflecting the electron beam a half track width with respect to the drawing position of the first elements and scanning the electron beam so as to fill in the shapes of the second elements, which straddle adjacent tracks, to draw the second elements.
