Of these only CD-ROMs use LASERs to access the data.
The others are magnetic storage devices.

Floppy disks use magnetic disk to store the data.

No. Floppy disks are magnetic media that rely on magnetic polarization to write data to the disk much like a hard drive. Unlike CD media they can be erased by a strong magnet field that effectively scrambles the data tracks.
Magnetic storage media are items like floppy and hard disk drives. They are based on magnetic transfer of data between the heads and the computer.
Hard disk drives, floppy discs, and VHS are some examples.
A floppy disk is a flexible magnetic storage medium encased in a semi-flexible plastic shell.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
Hard Disk Drive, Floppy Drive
A "diskette" or "floppy disk" is neither as they are removable magnetic storage media. However, if you refer to the drives that read from them or write to them, then those drives are considered hardware.
