Master information carrier for magnetic transfer and a method for producing the carrier

摘要

A method of producing a master information carrier by scanning a track a number of times. The method produces a master information carrier has a pattern of a magnetic layer representing information to be transferred to a high-density recording slave medium where the track width is not larger than 0.3 mum. The pattern is drawn by scanning a given track a plurality of times with an electron beam whose drawing diameter is smaller than the track width.
