Abstract

PURPOSE:To stably obtain an optical disk which excels in the uniformity of a recording film, recording characteristics and durability by forming the recording film by a DC sputtering method. CONSTITUTION:The DC sputtering method is used at the time of producing the optical disk including a stage for forming the recording film on a substrate by sputtering. The optical disk subjected to the film formation by the DC sputtering method has the excellent uniformity in the film thickness distribution and compsn. in the disk, deceases the fluctuations between batches and is suppressed in the increase of BER even in a durability test. The mass production, on an industrial scale, of the optical disks each formed with the recording film having the excellent uniformity and durability and high recording characteristics on the substrate is thereby enabled.
