Abstract:
A spinstand of a magnetic head and disk tester including a balancing system for balancing rotating components, comprising:A. a disk support assembly including:i. spindle support coupled to a base member;ii. a spindle, rotatable with respect to said spindle support about a spin axis;iii. drive means for selectably driving said spindle to rotate about said axis; andiv. means for producing an position signal representative of an angular position of said spindle with respect to said spindle support;B. at least one balancing assembly affixed to said spindle said balancing assembly being rotatable with said spindle about said spin axis and having interior thereto a plurality of balancing weights, each weight being adjustably positioned along an associated path, said paths being at least in part radially directed with respect to said spin axis; and,C. means for generating a signal, representative of radially directed acceleration of said spindle with respect to said base member, as a function of the angular position of said spindle about said spin axis.
