Abstract:
A rotating magnetic disk drive data storage device, comprising:a disk drive base; a rotatably mounted disk and spindle assembly, said disk and spindle assembly comprising at least one rigid disk for recording magnetically encoded data on at least one surface of said at least one rigid disk, said at least one disk being permanently mounted on said disk and spindle assembly; a spindle motor rotating said at least one rotatably mounted disk and spindle assembly; a movable actuator supporting at least one transducer head, said actuator positioning said at least one transducer head to access said magnetically encoded data on said at least one surface of said at least one rotatably mounted disk; and a disk constraining mechanism operable to constrain said disk and spindle assembly from rotating at least some of the time when said disk drive data storage device is not operational; wherein said disk constraining mechanism comprises control electronics providing drive current to at least one of pole of said spindle motor to hold said disk and spindle assembly in place.
