  • Method and apparatus to move an accessor within a data storage and retrieval system
    Patent number: 6988020
    Abstract: A method to move an accessor capable of accelerating at aMAX. The method calculates a first velocity profile where the accessor travels a distance in the minimum time interval. That first velocity profile requires a first maximum acceleration change. The method calculates a second velocity profile, where that second velocity profile includes a second maximum acceleration change, where that second maximum acceleration change is less than the first maximum acceleration change. The method determines if the accessor reaches aMAX using the second velocity profile. If the accessor does not reach aMAX using the second velocity profile, then the method moves the accessor using the first velocity profile. Alternatively, if the accessor does reach aMAX using the second velocity profile, then the method moves the accessor using the second velocity profile.
