发明名称 Content recording/reproduction device, content recording/reproduction method, information processing device, and content recording/reproduction system
摘要 There is provided a content recording/reproducing apparatus that can restore a deleted content. An MD recording player ( 1 ) as an example of the content recording/reproducing apparatus records, each time a content recorded in a mini disk ( 90 ) is deleted, information on the deleted content to a deletion history. Since a personal computer ( 200 ) as an external device re-records the content deleted in the MD recording player ( 1 ) on the basis of the content of the deletion history, so the user has not to re-record the deleted content by remembering what the deleted content was. Also, even if a content checked out to the MD recording player ( 1 ) is deleted, the number of times of check-in or check-out is matched with the content data by making deemed check-in on the basis of the deletion history or recording history. Thus, even if checked-out content data is deleted at the check-out destination, a limited number of times of check-out can be assured so that it is possible to prevent the content data from becoming unusable.
