Optical State Storage
This refers to the storage of data of an optically readable medium. This uses a laser to read the data off the optical storage device. Some examples of these are: CDs, DVDs and blue ray. There are some advantages:

DISADVANTAGES:
It is not re-usable, though it is great for archiving it can not be re-used which can be considered as disadvantage.
The writing time is considerably long and increases the time needed to write and re-write and restore data.
Magnetic Storage
This refers to data being stored on a magnetized medium. For Example Credit Card strips and Floppy discs.
Advantages:
very fast to access data.
Data can be read directly from any part of the hard disc.
