Magnetic recording/playback apparatus uses a flexible sheet record 36 which, on insertion through an opening 56, Fig. 1, is driven by rollers 64 and 68 and their associated pressure rollers 43 and 72 between guides 32 and 34 arranged so that the record takes the form of a belt, the gap between the ends being closed by driving roller 68 faster than roller 64. The record is provided with sprocket holes which drive a sprocket wheel 92 which drives a lead screw 90, Fig. 3, adapted to traverse a magnetic head 88 across the sheet. At the end of a record the carriage 86 of the magnetic head reaches the end of its traverse (extreme right in Fig. 3) and an extension 114<1> passes through an opening 148 to engage a cam surface 156, movement of which causes a gate 50, Fig. 1, to open and allow the record to pass out through an opening 54. The gate 50 may also be operable manually. When the record ceases to engage a record sensing member 120, the latter pivots and causes movement of a rod 137 which causes the carriage 86 to disengage from lead screw 90 and engage a lead screw 98 which is driven from the main driving means and causes the magnetic head to return to its starting position. Insertion of a new record rotates the sensing member 120 and causes the carriage 86 to be driven again by lead screw 92. Automatic record changing.-The record/playback apparatus in Fig. 9 has an extended baseplate to which a record changing mechanism 160 can be secured, and has a different record sensing means including a roller 210 and an arm 212.
