ABSTRACT:
A disk texturing apparatus for texturing surfaces of a magnetic disk or the like with cross-pattern grooves. The texturing apparatus is basically constituted by a rotational drive having a spindle for supporting and rotating a disk, and a tape transport mechanism for moving a texturing tape across and in pressed with a texturing surface of said disk. The spindle of the rotational drive mechanism is arranged to hold a disk in an eccentrically deviated position off the rotational axis of the rotational drive. As a result, the disk is revolved along an eccentrically deflecting orbit around the rotational axis of said rotational drive while being rotated with the spindle, moving in and out in radial directions in a degree commensurate with the amount of deviation from said rotational axis to form cross-pattern grooves on the disk surface.
