Tape driving apparatus and recording medium

A tape driving apparatus, comprising:

• tape driving means for running a magnetic tape accommodated in a tape cassette and for recording/reproducing information to/from said magnetic tape;
• memory driving means for reading/writing management information from/to a memory provided in said tape cassette for recording management information for managing the recording/reproducing operation of said tape driving means;
• divisional information detecting means for detecting logical position information corresponding to a plurality of positions on said magnetic tape physically and equally divided in a longitudinal direction thereof and for detecting divisional information indicating a divisional position unit;
• target position setting means for setting a position on said magnetic tape corresponding to one of said plurality of positions corresponding to said logical position information as a target position;
• target running amount detecting means for detecting a target running amount based on said logical position information and on said divisional information from a current position of said magnetic tape to said target position;
• actual running amount detecting means for detecting an actual running amount from a time when said magnetic tape has started to be run by said tape driving means;
• and
• control means for running said magnetic tape without reading logical position information or divisional information from said magnetic tape until at least the actual running amount reaches the target running amount while detecting the actual running amount from the time of starting the run, wherein said management information contains flag information indicating whether a high speed search function is enabled and said control means controls the running of said magnetic tape in response to said flag information.
