An information recording apparatus and method can prevent an information recording medium having a plurality of recording layers from being incompatible with a reproduction-only information recording medium due to an unrecorded area, which is produced by completion of recording in a middle of a data area of the recording layer. The apparatus is portable and it includes or is coupled with at least one subscriber identification module capable of storing one or more security codes which are used in a security code check for controlling usability of the at least one subscriber identification module with the apparatus. The washing unit includes a sink and a valve. A moderator, also stored on the data server, is used to enforce the rule enforcement logic corresponding to the application when a client attempts to perform an action to a data object associated with the application. The compensation signal increases the voltage at the first terminal whilst the output circuit generates the output signal.
