C-98 (49 minutes per side) in a clear CHROME NOTCH HI DEF cassette shell with anti-resonance independent bridge, tabs out, blue leader, loaded with vintage (pre-2000) Hi-Fi music grade audio tape.
NOTE: this is good vintage normal bias tape accidentally loaded into a chrome notch shell. It is not possible to record or playback properly on auto-sensing cassette decks without taking some steps like putting adhesive tape over the sensing notch.
