Patent attributes
A storage component interconnected via a network includes a recording unit for recording various contents, a first management table, a second management table and a control unit. The first management table manages for each user storage capacity in use by users in each recording unit of the storage components on the network. The second management table manages for each user total storage capacity that each user is allowed to use in all the recording units of the storage components on the network. The control unit restricts the storage capacity in use by the users so that the storage capacity used by the user does not exceed the total storage capacity that the user is allowed to use, on the basis of the first management table and the second management table.
