Abstract: PROBLEM TO BE SOLVED: To simplify an operation backing up data of same contents into a plurality of magnetic tapes, and furthermore, to shorten the time of the backing up operation being applied to a magnetic record reproducing device and an information processing device, such as an operation by which the data are backed up using a computer. SOLUTION: A plurality of record reproducing parts 8, 9 perform download processes simultaneously in parallel, reproduce the data simultaneously in parallel, and upload them selectively.

Abstract: PROBLEM TO BE SOLVED: To shorten the time required for the access start of a magnetic tape much more than before by applying a magnetic recording/reproducing device to a tape streamer for backing up data of such as a server. SOLUTION: When performing loading, before performing servo locking, information necessary for the access of the magnetic tape is made acquirable by the selective acquisition of data reproduced correctly.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device and bad spot detecting method which are capable of detecting bad spots more surely than heretofore when applied to a tape streamer for backing up the data of, for example, a server, etc. SOLUTION: The data is recorded in such a manner that the bad spots may be specified by any tracks or track sets in the recording units succeeding to at least the bad spots and the bad spots are detected by the data recorded in the manner described above.

Abstract: PROBLEM TO BE SOLVED: To perform high-speed access after insertion of a cartridge and to easily protect the data of a tape position in the ejection of a cartridge. SOLUTION: A tape is divided equally between the logical head and the end, and an ejection position candidate ID is set. When a candidate ID is found in a record of user data UD1, retry processing is performed even when no error exists in the nest data UD2. The same data UD2 is recorded repeatedly by the number of times a region having possibility of being damaged is included in the ejection/insertion of a cartridge, and an ejection region is created. The ID of the position is stored in a memory making the approximate center of the ejection region as the ejection/insertion position. The next user data UD3 is recorded succeeding to the ejection region. In the ejection of a cartridge, a tape is moved to the ejection/insertion position ID. Since the ejection region is created by retry processing, the ejection region is easily created and since the same user data are repeatedly recorded in the ejection region, data is protected from damage.
