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.
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".
both sides (poles) of a magnet have the same magnetic charge
The primary reservoir drive mechanisms are (1) Gas drive which includes both solution gas drive as well as gas cap drive (2)Water drive (3) Gravity drainage and (4) Combination drive.
Everything that humans use is part of a technology. Some of these technologies even predate modern humans. No modern human has ever lived that did not make use of hundreds of different technologies every day of their lives. The total number of technologies (including both actively in use and those considered obsolete) is so large as to be impractical to count and has been growing since before the existence of modern humans. Since the industrial revolution in the early 1800s the rate of growth of the number of new technologies has become exponential with the result that now within a period as small as one to two decades more new technologies get created than all of the technologies modern humans had available to them before the industrial revolution.

Iron and Nickel both have magnetic properties.

No, Steel itself is nnot magnetic, but some stainless steel can be made magnetic depending on how they were worked. Silver has very week, negative reaction to magnetic field, this is called diamagnetic.

An electromagnetic field is a physical field produced by electrically charged particles. It consists of electric fields and magnetic fields that interact with each other. When both electric and magnetic fields coexist, they form an electromagnetic field.
Not quite. An electromagnetic field is formed when electric and magnetic fields oscillate together perpendicularly to each other. So, a situation where both magnetic and electric fields are present and oscillating in a coordinated manner is what creates an electromagnetic field.
When a nail and a paperclip stick together due to magnetism, it is called magnetic attraction. This occurs because both the nail and paperclip are made of ferromagnetic materials, which are attracted to each other by magnetic force.
No type of magnetic mineral found in nature is properly called "platinum" by a chemist, because platinum is a chemical element and is not magnetic! The most common magnetic mineral found in nature is called "magnetite". It contains both iron (II) and iron (III) oxides in nearly constant proportions.
A reservoir drive mechanism is that mechanism in which oil is derived by water or gas or both water and gas drive the oil from the well. Is called reservoir drive mechanism.
Yes, an electromagnetic field refers to the combination of electric and magnetic fields that are generated by electric charges and changing magnetic fields. This field propagates through space and carries electromagnetic energy.
