Abstract
Parameters characterizing physical operation of a rotating structure (disk drive) are determined by sending appropriate commands and examining the response. The measured parameters are then used to balance various requirements. For example, when starting retrieval of a data stream, a speed which leads to highest effective retrieval rate may be used such that the data elements are available quickly for use. On the other hand, in a playback mode (or a shock mode), a speed which consumes the lowest amount of electrical energy can be used.
