Abstract

According to at least one embodiment, a method, a computer system, and a computer program product for enhanced dynamic braking of a tape storage device during a loss of power is provided. The present invention may include identifying a direction in which tape is moving; identifying a position of the tape; setting brake/coast conditions, wherein the brake/coast conditions comprise a BrakeSelect value of a supply reel and a BrakeSelect value of a take-up reel, based on the identified direction in which the tape is moving and the identified position of the tape; and based upon a detection of a loss of power, applying the set brake/coast conditions to the supply reel and the take-up reel.
