disk transfer is parallel , that's why ..


yes, obviously we should focus on all the datas coming from all surfaces. Not from only one surface...

and from all surface data is coming at a same time is not it ? so it is parallel ..

Yes, in second part , it should not be multiplied by 8 .. as to transfer data we consider single surface only.

How many Read/Write Heads is not mention per surface.. if it is 1 Read/Write Heads per surface then we need to multiply and if it is 1 Read/Write Head for all surface then no need to multiply .

what is default case ? i think default is 1 Read/Write Head per  surface but we consider a single surface when calculate data transfer rate  .. so no need to multiply with #of surface here in part B .

See this picture , we need to read data from each surface so for each surface R/W head is require :

This is the Default approach . And practical approach too..

But for our convenience we consider only 1 surface , it reads from one surface at a time. As data transfer rate is measured wrt a single surface .

Hence we no need to multiply with #of surfaces here.
