A system for calibrating servo marks formed in a tape medium includes an emitter for directing a beam of radiation toward the medium to form one or more servo marks. A detector detects the images of the marks, and determines one or more parameters of the marks. The controller adjusts power of the ra...

description A system for calibrating servo marks formed in a tape medium includes an emitter for directing a beam of radiation toward the medium to form one or more servo marks. A detector detects the images of the marks, and determines one or more parameters of the marks. The controller adjusts power of the radiation beam based on the parameters.
