MAGNETIC RECORDING AND REPRODUCING DEVICE AND ACCESS METHOD FOR MAGNETIC TAPE

摘要

PROBLEM TO BE SOLVED: To enable a user to access a desired file in a shorter time than heretofore, when a magnetic recording and reproducing device and a pad spot detecting method are applied to a tape streamer to back up the data of, for example, a server, etc. SOLUTION: A magnetic tape 10 is unloaded in an unloading region of nearly an intermediate position of an area recorded with user data for the unloading regions ARU0, ARU1, ARU2, etc., set with prescribed intervals in the longitudinal direction of the magnetic tape 10 or the magnetic tape is unloaded by changing over the regions between the unloading region, corresponding to the position instructed by a host device and the unloading region in such intermediate position.
