A large capacity disk in which information of not less than 50 Gbit can be stored and a method for manufacturing the same are provided. In the present invention, a disk for an apparatus for storing information of super high capacity, which can be mass produced at low costs, is manufactured by forming a Cr layer and a magnetic layer on the seed layer, using a three-dimensional island grown particle of nm scale as the seed layer without performing E-beam lithography. In the disk manufactured as mentioned above, it is possible to control the information storage capacity as desired since it is possible to control the size of the single domain, i.e., the bit according to deposition conditions. Also, the domains manufactured as mentioned above are not coupled with each other. Accordingly, the signal-to-noise ratio is high.
