Abstract

When a copy of music data recorded in an HDD to another electronic equipment is instructed, an accounting process is performed or a sound quality deteriorating process is performed based on a selection. When the accounting process is performed, after a predetermined accounting procedure is performed, a data copying process is performed and the data is outputted to a copy destination. When the accounting process is performed, a quality of the data is held to be almost identical to that of the original data. When the sound quality deteriorating process is selected, a data conversion is performed by a predetermined sound quality deteriorating process, the quality of the data is deteriorated, and the deteriorated data is outputted to the copy destination. In this case, the accounting is not performed. Where the data is moved, the accounting process and the sound quality deteriorating process are not performed.
