BASF ferrochrom 90 Compact Audio Cassette

SM Security Mechanism. BASF Trade Mark.

Black body with dark blue and white label. Yellow and white lettering.

No idea what a security mechanism on a cassette is, apart from those tabs you snap on the top.

  1. Believe BASF’s security mechanism is their patent pending plastic guide pins inside the cassette on both the supply and take up reel to prevent tape jam.
