This invention is a data storage system for accessing data stored in a data storage medium. Thus, the height of the hydraulic actuator andor manual override operators can be varied depending on the necessary configuration. The method includes receiving signals using directional reception; receiving positional data; calculating a correction amount; and applying the correction amount to subsequent uncorrected bearings to provide corrected bearings. The driving method of the liquid crystal display panel includes the following steps. The present invention also relates to a process for using sorbic acid and its salts for protecting wood from microbially induced degradation.
