I encountered this term in the following text of this article:
Four years later, he was looking for ways to grow his small magazine and started selling mail order records to the students who bought the magazine. The records sold well enough that he built his first record store the next year. After two years of selling records, he decided to open his own record label and recording studio.
I especially have trouble with the meaning of record here: Usually, a record is something done with a camera or something similar. However, this does not make much sense here, at least not for me.
Could you please explain the meaning and the context in this text? Thank you!
