  • Publication number: 20050069284
    Abstract: An apparatus for recording/reproducing information includes an externally-inputted information recording device and a reproducing device. An information amount checking device checks an amount of information of record information and/or information as recorded, when recording one of them on a recording medium. A recording capacity checking device checks a recording capacity of the recording medium on which the information is to be recorded. A judging device judges based on the checked information amount and recording capacity, as whether or not the whole of the information can be recorded on the recording medium. A dividing device divides the information into partial record informations each having an amount of information is equal to or smaller than the recording capacity. A partial information recording device repeats record of the partial record informations on the recording medium to record them thereon.

  • Publication number: 20030110295
    Abstract: An automatic URL link destination correcting system is provided to ensure an access to a Web site even when the URL has been moved to a new location. When an automatic URL link destination correcting apparatus attempts to access a Web site based on information recorded in an information recording medium, such as a CD or a DVD, it sends URL data designating the URL of the Web site or site identifying data related to the Web site recoded in the information recording medium to a URL managing server managing URLs of Web sites. The URL managing server then searches through the URLs of the Web sites it manages, and judges whether the URL corresponding to the URL data or the site identifying data has been moved to a new location. When it is judged that the URL has been moved to the new location, it returns updated URL data designating a URL indicating the new location.
