摘要： A control system and method for operating a system comprising a host computer, a buffer, a tape drive and a tape is provided. The method includes writing data to the tape while the tape is traveling at a first speed; stopping the tape; determining a minimum distance to reposition the tape; and, thereafter repositioning the tape.

摘要： A method and apparatus for preventing the detachment of an end of tape from a hub filler during movement of the hub filler along a guide rail during an unloading operation of a tape drive mechanism. Detachment is prevented by a retracting tape dragging the hub filler along the guide rail, so as to maintain adequate tension that prevents detachment of the tape from the hub filler. The hub filler, which is coupled to the tape, guide arm, and guide rail, provides adequate drag force to maintain tension in the tape and prevent damage to the tape or the tape drive mechanism.

摘要： A method of loading a tape from a single reel tape cartridge into a take-up reel. Position sensors detect position of a guide arm as a tape loading mechanism loads and unloads tapes from a single reel tape cartridge. The position sensors are accurate and eliminate problems that occur from small misalignments of hub filler access with the access of the take-up reel. Further, the position sensors enable the hub filler to consistently attach to a leader pin at the end of the tape of the single reel tape cartridge without frequent malfunctions.

摘要： A reel-to-reel tape system stops movement of the tape during a power loss situation without overrun by one of the tape reels and without causing undue stress upon the tape itself. If rotational momentum of the supply reel is sensed to be disproportionately larger than the momentum of the take-up reel, supply motor back emf for dynamically braking the supply reel is applied while also driving the take-up reel in the direction of rotation in which it operated when the power source was discontinued. An appropriate amount of tension is maintained on the tape until the tape motion has come to a complete stop. A capacitor large enough to supply the power needed to provide current to the power bridge of the motor drivers is provided. The capacitor is charged upon power up of the drive and is not tapped unless and until the normal supply voltage of the motor drivers is turned off. The take-up reel motor is provided with optimum current to take up the loose tape that otherwise would be produced in the tape path and around the reels, thus preventing a hazardous situation.
