for using CDs, DVDs, and Blu-ray discs to listen to music or watch a movie.
Most drives also allow you to write data to a disc, so you can create your own music CDs, video DVDs or even create of back-up copy of your important data files.

Answer:
The class of language the machines recognise is Regular Language (See Explanation Below)
Explanation:
Given
Form δ : Q × Γ → Q × Γ × {R, S}
From the above transition form, it can be seen that the machine cannot read square symbols passed to it.
Regarding the square the machine is currently reading, there are multiple movement of S and it shouldn't be so because any number of the multiple movement can be simulated by exactly one movement of S.
As stated earlier that sequence of moves can be simulated by just one movement.
Let R = the movement
This means the machine can only use right move efficiently.
With this, we can say that the machine only read input string.
This is a characteristic of DFA (Deterministic Finite Automata).
With this, we can conclude that some DFAs will simulate the Turing machine and that they only read regular language.
Because it downsized the scale of the computer itself.
