Answers
Answer: A Computer stores all its data and instructions in its storage space which is known as memory.
Since a computer is digital logic device, the information or any type of data written on harddrive is either logical 1 or 0.
Here I'm assuming you're talking about HDD not SSD.
Before talking about “How data is being written on hard drive?”. Let me give you a short information about an HDD
An HDD is data storage device used in computers to store user data. It has either two connection slots SATA or BUS CABLE out of which one is the 4-pin connector. An HDD consists on mainly following 4 parts:
Platter - The platters are the circular discs inside the hard drive where the 1s and 0s that make up your files are stored.
Spindle - The spindle keeps the platters in position and rotates them as required. The revolutions-per-minute rating determines how fast data can be written to and read from the hard drive.
The R/W arm - The read/write arm controls the movement of the read/write heads, which do the actual reading and writing on the disk platters by converting the magnetic surface into an electric current.
Actuator - The actuator or head actuator is a small motor that takes instructions from the drive's circuit board to control the movement of the read/write arm.
Working - When your computer stores data on its hard drive, the spindle rotates the platter, now since the platter is nothing but an aluminium disc, being an metal aluminium exhibits the property of magnetism. From here the R/W arm consists of an strong electromagnet, which when controlled by a actuator, heavily magnetization is being done on a particular block present on the disk of platter. As I mentioned earlier in any digital logic device the data is being stored either with logical 1(true) or 0(false). Similarly if a block if magnetized then it is with logic 1 Which means there is a data on hard drive vice-versa with non-magnetize block.
The data is stored in a very orderly pattern on each platter. Bits of data are arranged in concentric, circular paths called tracks. Each track is broken up into smaller areas called sectors.
