According to the invention, techniques for recording data onto recording media at relatively high transfer rates for relatively long periods of time. The invention also relates to the use of sorbitan carboxylic acid ester in washing or care formulations. 06 gcm3, a maximum tensile force of between 9. The strobe-offset control system effectively removes the detected phase difference between the data signal and the strobe signal. The data set may be changed by alternately writing a new value to a different flag cell in each successive change of the data set. The locking unit includes retaining members having a retaining unit sandwiching the movable vibration-correcting lens and arranged to slide along the direction orthogonal to the optical axis; and the actuating unit switches between the locked state and the unlocked state by moving the retaining members in opposing directions.
