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

magnetic storage device
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 cassette is a magnetic storage device. It uses magnetic tape to store audio or video recordings, allowing data to be recorded and played back using magnetic heads. Unlike optical storage devices, which use lasers to read and write data on discs, cassettes rely on magnetic fields to encode information.

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.
It is not an optical device. C D ROM or DVD are optical devices. Whereas a digital memory card is solid state device.
No, its not an optical storage 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.
