Disk storage is a broad category of storage mechanisms where data is recorded by various optical, mechanical, magnetic or electronic changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism.

Notable types are:-

the floppy disk drive (FDD)
the hard disk drive (HDD)

Digital disk drives are block storage devices. Each disk is divided into logical blocks which are collection of sectors. These blocks are addressed using their logical block addresses (LBA). Reading or writing operations happens on granularity basis on these sectors.
