In an electronic musical apparatus, a media ID (MD1, MD2, MD3, MD4, MD5) is associated with each recording media of a memory card 8, hard disk device 10, flash memory ROM 11, CD-ROM 12 and internet 15. Each media ID is encrypted to be recorded on a different position in a ROM 2. Upon reading a music content, the media ID of the corresponding recording media is decoded to decode the music content based upon the media ID and the secret key, and then, the resultant is temporarily stored in a RAM 3. Upon writing a music content, it is encrypted based upon the media ID corresponding to a recording media and the secret key, and the content in the RAM 3 is deleted. This makes cryptanalysis hard to thereby enhance a protection level of a music content in an electronic musical apparatus.

There is provided a generator which produces electromotive forces in the same direction on all windings to prevent occurrence of leakage magnetic fields of the windings and lowering of the rotational forces of rotor plates due to the leakage magnetic fields from the windings and offers high efficiency without accompanying any circuit loads. The generator includes first windings 15-1 to 15-4 divided in the plural number and wound around a fixed ring core 5; second windings 25-1 to 25-4 divided in number equal to the plural number and wound around so as to cover divided gap portions of the first windings; and first and second rotor plates 30 and 35 provided to be opposed to both surfaces of the ring core 5, wherein the first rotor plate has first permanent magnets 40-1 to 40-4 opposed to the first windings, the second rotor plate has second permanent magnets 45-1 to 45-4 opposed to the second windings, and electricity generated on the first and second windings 15-1 to 15-4 and 25-1 to 25-4 is taken out by rotation of the first and second rotor plates 30 and 35.

An apparatus is designed for using a music content composed of at least one content material in accordance with security information of the music content. In the apparatus, a reading section reads a recording medium which records a data file of the music content having a chunk structure including a content material chunk and a security information chunk. The content material chunk contains substantial data of the content material and identification information for uniquely identifying the content material. The security information chunk contains security information of the content material and identification information for uniquely identifying the content material. A using section permits use of the content material when the identification information read from the content material chunk coincides with the other identification information read from the security information chunk.
