Prior to 1989 is was necessary to display a copyright notice in order to maintain protection on a work. That year the US signed the Berne Copyright Convention which standardized copyright law across national borders. One of the provisions that Berne contained was that a copyright notice would no longer be required. US law was amended to bring it into compliance.
The law has changed and the copyright symbol is no longer needed to insure the protection of the copyright owner. The symbol for copyright is: ©
In the US, since copyright law was amended in 1989, it has not been necessary to display a copyright notice for protection.

Under US copyright law, there are no recordings that are public domain; they are either covered under state copyright law prior to 1972, under federal copyright law if published after that, and under federal copyright law if they were never published at all. The only possible public domain records would be some that were published before 1989 and after 1972 without the necessary copyright notice or registration.
Yes it, in all likelihood it is an infringement of copyright. Whether or not a copyright symbol is displayed has no bearing on the materials copyright status. Since the law was amended in 1989 it has not been required to have a copyright notice in evidence to maintain protection.
Under US law a copyright notice has not necessary since 1989, for a work to be protected
No. Since 1989, when copyright law was amended to bring it into alignment with the Berne Copyright Convention, it is no longer necessary for a copyright symbol to be displayed to establish or maintain protection. Copyright exists from the moment you create an original work, and that can be something as simple as a photo of your child.
Copyright law is a federal law, granted in the Constitution.
Copyright law.
Legally, nothing. There is no requirement to have a copyright or trademark notice in order to establish intellectual property rights and hasn't been since 1989 when copyright law was amended to bring it into alignment with the Berne Copyright Convention.
