In a magnetic disk drive, a special device called a read/write head is used to read data from and write data to the magnetic disk. The head floats just above the surface of the spinning disk, allowing it to access the magnetic fields that represent stored data. As the disk rotates, the head moves across the surface to locate the appropriate data tracks, enabling fast access to information.
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
It is a input:)

In a magnetic disk drive, the special device that reads and writes data to the disk's surface is called a read/write head. This head operates at a very small distance from the disk platter, utilizing magnetic fields to detect and alter the magnetic orientation of the disk surface, thereby enabling data retrieval and storage.
A disk drive is all three, depending on the situation. It is an input device when it provides stored data to an application. It is an output device when it receives data from an application. It is a storage system when it saves the data for future use.
A disk drive.
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.
Permanent storage device such as a hard drive.
Hard Disk Drive, Floppy Drive
Data storage device that reads and writes data on a magnetic tape.
A tape drive is a device that stores computer data on magnetic tape, especially backup and achieving purpose.
A floppy drive is an I/O device that uses removable magnetic media coated on a film similar to magnetic recording tape, but formed into a disc shape within a holder.
