The third level (high-impedance state) invokes the power-down mode for standby condition. Gain switch R/W is used to reduce the gain during writing. During CD-R writing with clipping, the high peak signals for the central and satellite segments are clamped internally and the output currents of the A, B, C, D, E, F, ...
