DEPOSITION METHOD FOR MONOMOLECULAR FILM OR MULTILAYER FILM THEREOF AND MANUFACTURE OF RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To form a uniform monomolecular film or multi-layered molecular film and carry out high density recording with excellent reproductivity and excellent reproduction of the recording by forming a first region and a second region in a substrate and carrying out film deposition on the first region prior to the film deposition on the second region. ;SOLUTION: A material for a substrate 11 to compose a recording medium may be one having conductive and smooth surface and materials such as gold, platinum, silver, palladium, etc., are examples of the material. At the time of depositing a monomolecular film or a multilayer film of monomolecular layers on the substrate 11, a first region 12 and a second region 14 are set in the substrate 11 and prior to the film deposition on the second region 14, film deposition on the first region 12 is carried out. The surface area ratio of the previous deposition region 12 to the recording medium-forming region 14 in a single substrate is not especially limited as long as the ratio is within a satisfactory range to carry out recording and reproduction of information on the recording medium-forming region 4. The length 15 of the recording medium-forming region 14 in the longitudinal direction of the substrate is however preferably 10nm or longer.;COPYRIGHT: (C)1997,JPO
