摘要： A communication apparatus and a communication method prevent responses from being simultaneously received from two or more communicating parties. A first NFC apparatus transmits data for requesting IDs, and acquires IDs sent from second and third NFC apparatuses in reply to the request. After acquiring the IDs of the second and third NFC apparatuses, the first NFC apparatus transmits data that includes their IDs as the data for the second and third NFC apparatuses. If the first NFC apparatus cannot properly acquire the IDs of the second and third NFC apparatuses, then it sends the data for requesting their IDs again. Upon receipt of the request for the IDs, the second and third NFC apparatuses generate their own IDs by using random numbers and send the generated IDs. If the second and third NFC apparatuses receive the request for their IDs again, then they re-generate their own IDs by using random numbers, and send the re-generated IDs again. The present invention can be applied to, for example, an IC card system.

摘要： Hard disk drive unit with buffer and cue data areas efficiently records files to magnetic tape. Recording and reproducing apparatus includes changer unit for selecting and carrying tape cassettes and accommodating magnetic tapes with predetermined recording areas, tape drive unit for loading tape cassettes and recording and reproducing magnetic tapes, hard disk drive unit having a buffer area for recording and reproducing data in the tape drive unit, and controller unit for managing recording areas of tape cassette magnetic tapes arranged in the changer unit as a continuously formed area. Storage level is set corresponding to remaining capacity of buffer area and remaining capacity of one BOF data area, or number of past access times to corresponding file in a file information table and final access time, etc. Based on storage level, control operations are performed. Frequently used file data can be selectively recorded to buffer or BOF data areas.
