Quizplus · Accepted Answer

Discs commonly store items in a single track that spirals from the center of the disc to the edge of the disc. This is known as a spiral groove or a spiral track. The items are arranged in a continuous spiral path that follows the disc's groove from the inside to the outside of the disc. This allows for efficient use of space and easy access to the items on the disc.
