Abstract

In one embodiment, a write controlling method is provided that adjusts the timing to wrap-turn the tape running direction depending on the data amount in order to reduce the time required for positioning in reading any data by performing back-and-forth data writing by positioning a magnetic head of a tape recording apparatus at a predetermined position close to a first end of the tape medium, writing data on the tape medium starting from the predetermined position toward a second end of the tape medium, wrap-turning a running direction of the tape medium when the magnetic head reaches the second end of the tape medium, and writing the data on the tape medium from the second end toward the first end.
