8 cm (3 in.) compact disc singles
Your compact disc player does not need an adaptor to play
compact disc singles. Compact disc singles are about 8 cm (3
in.) in diameter-smaller than standard discs.
NOTICE
Do not use an adaptor for compact disc singles — it
could cause tracking errors or interfere with the ejection
of compact discs.
