Abstract
The present disclosure generally relates to increasing storage capacity for magnetic media dual-reel tape devices, and more specifically modifying the writing process to the magnetic media. Rather than having an unused acceleration zone, portions or even the entire acceleration zone on the tape can be used to store data. To achieve the acceleration to a predetermined speed, the tape is wound in the opposite direction from where the writing and/or reading will occur. The winding is of a sufficient distance to create sufficient distance along the tape for the acceleration to the predetermined speed to be completed by the time the writing and/or reading location is reached. Furthermore, when the acceleration zone is completely used for data, writing can occur from the beginning of the tape to the end of the tape rather than writing to/from the acceleration zone and then returning to a corresponding end of the tape.
