user24309: Is the FIDE rule for writing chess moves with pen and paper by both players discarded or not mandatory in World chess championship games?
In case yes, why it is discarded or not mandatory to write chess moves?
If i am not wrong, the players were writing the moves on paper.

user24511: Most major tournaments (including the World Championship) are commonly played on DGT Boards which automatically record the notation for the players. This has some distinct advantages;

Legibility
Improved ability for broadcasting
Reduces need to transcribe games after the fact into a digital format.

That being said I believe it is still a requirement for players to manually record there games. I don't believe these records are discarded as they are submitted to the tournament organisers who technically own them.
In regards to why pen and paper. It minimises opportunities and accusations of cheating. If I was playing over the board to you and was entering in each move onto a computer (through something like chess base) who is to say I didn't enable an engine to quickly analyse a move?
