Enhanced dynamic braking algorithm for tape storage device

A computer system for braking of a tape storage device during a loss of power, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• 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.

A computer program product for braking of a tape storage device during a loss of power, the computer program product comprising:

• one or more computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor to cause the processor to perform a method comprising:
• 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.
