Abstract: The amount of light reflected from a disk is detected, and it is determined according to the amount of reflected light whether the disk is a recordable disk or a rewritable disk. The disk is controlled according to the result of determination such that it is rotated at a constant angular velocity (CAV) or at a constant linear velocity (CLV) and recording is executed. Further, rotation driving control of the disk is selected according to factors other than the type of the disk, such as according to whether random recording is allowed or not, according to a recording state in the disk, according to whether an alternative area is provided or not, according to a recording start position, or according to whether initialization is required or not. CLV control or CAV control is appropriately selected for a disk at recording to suppress a reduction in accessibility and a reduction in data transmission rate.

Abstract: When a radio communication is made between a predetermined base station and a communication terminal, the communication terminal is allowed to make a communication if a predetermined registration processing is made. If the above registration processing is not executed, then predetermined functions other than a communication function of the communication terminal are limited. Moreover, when a predetermined operation mode is set by an operation means, at least a transmission processing at a radio communication means is stopped and an execution of predetermined functions other than the radio communication processing is not restricted. Thus, when a communication terminal apparatus incorporates therein other functions than an audio reproducing function, operation of such function can be limited properly.
