Magnetic Disk Structure
In modern computers, most of the secondary storage is in the form of magnetic disks. Hence, knowing the structure of a magnetic disk is necessary to understand how the data in the disk is accessed by the computer.
Magnetic Disk
Structure of a magnetic disk
A magnetic disk contains several platters. Each platter is divided into circular shaped tracks. The length of the tracks near the centre is less than the length of the tracks farther from the centre. Each track is further divided into sectors, as shown in the figure.
Tracks of the same distance from centre form a cylinder. A read-write head is used to read data from a sector of the magnetic disk.
The speed of the disk is measured as two parts:
Transfer rate: This is the rate at which the data moves from disk to the computer.
Random access time: It is the sum of the seek time and rotational latency.
Seek time is the time taken by the arm to move to the required track. Rotational latency is defined as the time taken by the arm to reach the required sector in the track.
Even though the disk is arranged as sectors and tracks physically, the data is logically arranged and addressed as an array of blocks of fixed size. The size of a block can be 512 or 1024 bytes. Each logical block is mapped with a sector on the disk, sequentially. In this way, each sector in the disk will have a logical address.

Discrete Mathematics Tutorials In Hin... Students search on youtube and google 'operating system lectures in hindi' but many website do not provide the good concepts so here is my channel which would guide you in all manner.
Operating system tutorials is one of that keyword which is being searched a lot on youtube and google so here guarantee again that this is that channel which help you lot in your university exams and as well as in practical’s.
My operating system videos in hindi covers all syllabus and students can download the notes which link will be in description also. My 5 years of teaching experience and my Btech Experience says that students love to watch operating system in hindi because in many colleges teachers teach by ppt and many by books but they do not clear the concepts.
My lectures and theory topics are covered as per many computer science field ,operating system tutorial for bsc. Students who searches for operating system tutorial for diploma course can also follow these videos and it will same beneficial as it is for Bsc students.
One more interesting thing is that i also covered operating system tutorial for ugc net as i have told lots of time that concepts is always same but it matters only questions. So i have covered lots of question of UGC NET operating system exams.
Lots of Students says sir they need separate ugc net operating system tutorials so here i also made lots of separate videos on ugc net operating system and also created separate playlist so they do not get confused in university exam videos.
My Channel covered all main previous year question papers of operating system.
Yes this is interesting that many students requested me for gate tutorials for operating system in hindi as they found my university exam videos very beneficial. so i also covered lots of GATE previous years question on operating system.
So students can watch my operating system videos for gate in my channel and if they have any query they can comment in the videos so i can help then in any manner is will. Thanks a lots to my subscribers and who watches my videos.
