ABSTRACT:
There is provided an electronic apparatus which once makes a user conscious of copyright and the like of digital data, such as audio data and image data, when the user records the digital data or performs the like processing, and then allows the user to use the digital data without annoying him any longer concerning the copyright and the like of digital data, a data recording method for the electronic apparatus, and a storage medium storing a program for executing the data recording method. The electronic apparatus is capable of performing a plurality of processes including a specific process execution of which is restricted in advance. A notification section notifies a user of a message calling the user's attention to the specific process in response to an instruction issued on the specific process. A function-setting section sets a specific function according to the notification of the message. An execution restriction-removal section removes restriction on the execution of the specific process and stops the function of the notification section, based on the set specific function.
