摘要： A liquid crystal device, and a method and an apparatus for driving the same in which the refractive index of the liquid crystal device is adjusted using a simple driving method and apparatus, which is advantageous in that the cost is reduced, are provided. A liquid crystal device (10) includes a first transparent substrate (1002) and a second transparent substrate (1004) that face each other, a liquid crystal (1014) filled between the first and second transparent substrates (1002, 1004), a first transparent electrode (1006) formed on a surface of the first transparent substrate (1002) that faces the second transparent substrate (1004), and a second transparent electrode (1008) formed on a surface of the second transparent substrate (1004) that faces the first transparent substrate (1002). First and second driving signals (S1, S2) of square waves are applied to the first and second transparent electrodes (1002, 1004) with a time interval t (sec) therebetween. Thus, the potential difference between the first and second driving signals (S1, S2) is applied to the liquid crystal (1014).

摘要： A reproducing laser output can be adjusted to an optimal level. To this end, a magneto-optical disk device includes a differential amplifier and a shortest recording mark identifier that detects a shortest recording mark reproducing signal corresponding to a component of a shortest recording mark in a reproducing signal obtained by reproducing a magneto-optical disk. In addition, an envelope detector detects an amplitude level of the shortest recording mark reproducing signal, a comparator compares the amplitude level with a reference voltage outputted from the reference voltage source, and a drive control section adjusts the reproducing laser beam to an output level at which the amplitude level is equal to or higher than the reference voltage, based on a comparison result from the comparator.
