发明名称 Information recording/play-backing apparatus
摘要 It is possible to save power in an HDD/optical disc combination camera. During a normal recording operated by a battery, only the hard disk is operated and operation of the optical drive is stopped. Alternatively, only the optical drive is operated and the operation of the hard disk is stopped. During dubbing, both of the HDD and the optical drive are operated when performing play-back/display during the dubbing and a large current is consumed. Accordingly, the operation is permitted only by external power supply. In the case of dubbing not performing play-back/display, the battery remaining amount is checked and dubbing is permitted only if the amount is equal to or greater than a threshold value.
