Patent ID: 8355036

Claim:
A record control signal generating apparatus for generating and outputting to a recording apparatus a control signal for forming a latent image, wherein said recording apparatus comprises: a beam deflection unit that moves an irradiation position of an exposure beam, a substrate velocity adjustment unit that adjusts a moving velocity of a substrate along a tangential direction or a radial direction, and a blanking control unit that performs blanking control of irradiation of said exposure beam, said recording apparatus irradiating said exposure beam on a resist layer on said substrate while moving said substrate at said moving velocity along the tangential direction or the radial direction adjusted by said substrate velocity adjustment unit, and forming a latent image, said record control signal generating apparatus comprising: a record signal generating unit that generates a record signal of record data to be recorded on said substrate; a characteristic information signal generating unit that generates a characteristic information signal corresponding to the characteristic information of said recording apparatus as a signal compensation element, the characteristic information indicating a pre-measured positional misalignment between a beam irradiation position and a center of rotation of said substrate; and a signal generating unit that generates a compensated control signal to at least one of said beam deflection unit and said substrate velocity adjustment unit according to said record signal generated by said record signal generating unit and said characteristic information signal generated by said characteristic information signal generating unit.
