What is the standard copyright text on CDs, cassettes or vinyl?
When it comes to music, there is both the copyright in the music itself (author, publisher or mechanical rights) which use the © symbol and the copyright in a recording which are the phonographic rights and use the Ⓟ symbol.
There is no set wording to use, however this statement is quite widely used and is fairly all-encompassing:
© & Ⓟ Your name/band name, year. All rights of the produced and of the owner of the work reproduced reserved. Unauthorised copying, hiring, lending, public performance and broadcasting of this recording prohibited.
In the above statement you would just need to change the words in italics to insert your name or band name and the year of the release.
This text often runs in a circle around the bottom half of a CD in smaller writing.
