Harddrive is magnetic.
Optical storage devices examples are CDs, DVDs etc.

A compact disk (CD) is an optical storage device.
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.

A conventional hard disk is magnetic.
A write head is the part of an electromechanical device which converts electrical signals into digital or analogue information stored on a magnetic or optical medium.
Storage device is something used to store the data. It has several types such as magnetic, optical, electronic etc. Talking about a computer, storage device may be removable or non-removable.
No, its not an optical storage device.
It is not an optical device. C D ROM or DVD are optical devices. Whereas a digital memory card is solid state device.
One storage device is RAM. Also Magnetic Media, Flash Media, and Optical media. Your welcome :)
Neither. They are removable magnetic storage. Optical storage consist of CDs, DVDs, etc.
optical memory: it is a memry device that uses laser beams ro store data . for e.g. CDROM. magnetic memory: it is a memory device that uses magnetic tape to store data . for e.g. hard disk optical memory are advanced and faster than magnetic memory device..
