Which storage devices typically use magnetic film or aluminum platters?

The correct choice identifies hard disks and floppy disks as storage devices that utilize magnetic film or aluminum platters. Hard disks operate with spinning platters that are coated with a magnetic material, allowing data to be written and read using magnetic heads. The data is stored in a magnetic format, which is fundamental to how traditional hard drives function.

Floppy disks similarly use a magnetic medium, where thin magnetic film is encased in a plastic shell. This magnetic film is where the data is stored, and it uses a drive to read from and write to the disk. Both of these storage devices rely on magnetic principles for data storage and retrieval, distinguishing them from optical media or solid-state technology.

Other options involve either optical storage or flash memory, which do not utilize the magnetic technologies described. For example, USB flash drives and SSDs operate using flash memory technology rather than magnetic platters, and CDs, DVDs, and Blu-ray discs are optical storage mediums that read and write data using lasers.
