ABSTRACT:
Method and apparatus for manufacturing a stretched surface recording disk wherein a laminate is formed by superposing magnetic sheets on upper and lower surfaces of a base with a bonding agent being interposed between the regions to be bonded, clamping both an outer annular portion and an inner annular portion of the resulting laminate, displacing the clamped inner annular portion including both magnetic sheets and the base relative to the clamped outer annular portion in a direction perpendicular to the surface of the base, thereby stretching the laminate and bonding the magnetic sheets to the base while the annular portions are so displaced.
