P应该是发行年代吧,publication的首字母。版权应该是C,copyright的首字母。

Source from http://en.wikipedia.org/wiki/Sound_recording_copyright_symbol:
The ℗ symbol, a circled P, is the copyright symbol used to provide notice of copyright in a sound recording.
The P stands for phonogram, the legal term used in most countries to refer to works known in U.S. copyright law as "sound recordings."
The sound recording copyright notice consists of three elements:
1.the ℗ symbol;
2.the year of first publication of the sound recording; and
3.an identification of the owner of the copyright, either by name, abbreviation or other designation by which it is generally known.
