Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
Optical storage device
A camera is an optical device that can produce a real image. It does this by focusing light onto a photosensitive surface (like film or a digital sensor) to create a true-to-life representation of the scene being captured.
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.

Input device
Use a pinhole or a dark-filtered optical device to project the sun's image on a light surface,and view the image.
Optical equipment is any device that uses light to perform its function.
A device to measure optical refraction.
A mirror is an optical device because it reflects light, forming an image by reflection. It works on the principle of specular reflection, where light rays are reflected at the same angle as they strike the mirror surface. This reflection process allows mirrors to create virtual images that can be seen by the human eye.
