There are three types of arms that your record player can come with: fully automatic, semi-automatic, or manual tonearms. A fully automatic one moves towards the record without you touching it and automatically returns to the beginning once the record ends. While a semi-automatic one must be manually placed on the record (or song of your choice), it also automatically returns to the beginning when the LP is finished. Finally, a manual arm is just that—you manually move it onto the record and must manually move the arm back when the record is over. Most retro record players have a manual tonearm, while newer turntables are fully automatic.
