    摘要: An electron beam irradiating apparatus according to an embodiment includes: a deflector configured to perform blanking or deflecting of the electron beam emitted from an electron gun, the blanking being performed based on a blanking control signal, the deflecting being performed based on a deflection control signal, or blanking and deflecting being performed based on the blanking control signal and the deflection control signal; a first clock signal generation circuit configured to generate a first reference clock signal having cycles which vary with a drawing radial position on the stage; a second clock signal generation circuit configured to generate a second reference clock signal having cycles which are independent of the first reference clock signal; and a control signal generation circuit configured to generate a first control signal that is at least one of the blanking control signal and the deflection control signal, based on the first reference clock signal and the second reference clock signal.

    摘要: It is made possible to fabricate a bit-patterned magnetic recording medium having a high recording density and making favorable address deciphering possible. An original disk fabrication method for irradiating a photosensitive resin film with an electron beam to draw a pattern, the method includes: irradiating the electron beam by using a plurality of blanking signals every rotation of a stage per bit unit, when drawing the pattern in a part corresponding to an address part on a photosensitive resin film.
