According to the Red Book specification.

You could call that a file system, but I doubt most OS or file-system design types would. There's very little indexing information. Each sector (holding 1/75th of a second of audio) includes a "subcode" byte that encodes the current track and time within it (the drive / player does not keep track of that).

(I worked for Philips' CD-I authoring tools group once upon a time.)
