A tone arm can be adjusted to hold the stylus in this position if there is to be exactly one record on the turntable. A changer, however, plays stacks of records, and the tone arm will bold the stylus perpendicular to only one of the records. The stack problem has other aspects, too. It increases the weight of the turntable which the motor is turning, and the turntable is likely to run slow as the stack builds up. Moreover, it never did a record any good to be dropped, and then to be gripped in the grooves of another record.
Record changers come in all varieties.
