A recording-and-reproducing apparatus for reproducibly controlling data recorded on a recording medium includes: a device configured to acquire control information required for reproducing the data when the data is recorded; a device configured to control operations during the period from the start to the end of recording data on the recording medium. The collector includes a collector electrode 2, heat conductive columnar ceramic elements 3, an outer collector enclosure 4 for maintaining vacuum and loss ceramic members 5 arranged between the outer surface of the collector electrode 2 and the inner surface of the outer collector enclosure 4. The mobile terminal device provides a reprint instruction for the attached file by replying the email. Expressions can be multi-valued, thus avoiding the need for naming intermediate results. The pegged data from the revelant records can then be used multiple times in a variety of statistical threads or windows rather than having each statistical thread engine peg the information it requires separately. Various forms of the system, apparatus and methods may be used for improved security, security provisioning, security management, and security infrastructure.
