Abstract: In an optical recording method and apparatus for an optical storage medium, a recording pulse pattern having a sequence of multiple pulses is used to record one of plural kinds of marks with different lengths on the storage medium through a variable-linear-velocity recording process or a constant-angular-velocity recording process. Two or more discrete write powers are individually allocated to the respective pulses of the recording pulse pattern. Each of the write powers, allocated to the respective pulses of the recording pulse pattern, is linearly varied in proportion with a change of one of the recording linear velocity and a recording position of the storage medium. The resulting recording pulse pattern is supplied to a pickup, and the pickup emits a light beam to the storage medium in accordance with the recording pulse pattern having the linearly varied write powers allocated to the respective pulses, so that one of the plural kinds of marks is recorded on the storage medium.

Abstract: To permit a switched-capacitor-type stabilized power supply device to operate stably until the battery power falls considerably low, it needs to be provided with a voltage step-up circuit with a high voltage step-up factor. However, inconveniently, in a conventional switched-capacitor-type stabilized power supply device, increasing the voltage step-up factor of the voltage step-up circuit increases the difference between the voltage stepped-up by the voltage step-up circuit when the battery voltage is still high and the set output voltage, and thus lowers power conversion efficiency.
