Abstract

A magnetic disc cartridge 1 comprises a jacket 2 which contains a rotatable magnetic disc having a hub 6 which receives a rotatable shaft which drives the disc. The jacket 2 has an opening 7 through which the rotatable drive shaft passes. When the disc is rotated, information may be recorded in a plurality of circular tracks thereon. The jacket 2 has an indicator 20 for indicating the number of tracks in which information signals have already been recorded. The indicator 20 includes a scale 28 and a rotatable member 21 having a keyhole-shaped opening 22, 23 which in operation is engaged by a shaft 30 of a recording apparatus, to be rotated by incremental angles each representing the recording of a track. The keyhole-shaped opening 23 also acts as a pointer indicating the track number. The rotatable member 21 may have teeth engaged with a resilient pawl 25 within the jacket 2, to restrain it against rotation when disengaged from the apparatus.
