How many cylinders are there for each platter in a Hard drive?
No. of Cylinders = No. of Tracks on each platter multiply by 2 for both sides since each platter stores information on both sides.
What is the function of disk platter in Hard Disk?
Computer hard disk drives may be made of a stack of one or more disks (made out of metal or ceramic) covered in a magnetic "paint". Each of these disks is called a "platter".
If a magnetic drive has four platters how many heads does it have?
Each platter on a hard drive has 2 heads.Every Additional Platter you can multiply x2Example:1 Platter x 2 = 2 Heads2 Platters x 2 = 4 Heads3 Platters x 2 = 6 Heads4 Platters x 2 = 8 Heads5 Platters x 2 = 10 HeadsETC...At least until some new hard drive Architecture comes into place.
What are the concentric magnetic circles that run around a disk platter called?
The concentric magnetic circles that run around a disk platter are called "tracks." Each track is a circular path on the surface of the disk where data is recorded. Data is organized in these tracks, and the read/write head of the disk accesses the information by moving to the appropriate track.
What is the same track on each platter?
A cylinder. Each track on each platter can be thought of as being a ring, thus if you isolated the same track upon each platter you'd have a stack of imaginary rings which would therefore form an imaginary cylinder.
Each surface of a polyhedron is called?
Each surface of a polyhedron is called a face.
How many read write heads are required for each hard disk platter?
2 per platter
What is each surface of a polyhedron is called?

Do hard drives have magnetic cylinders that store information?
Yes. The magnetic 'platters' that store the information are arranged horizontally and are 'read' by an arm that swings over them. Think of an album on a turntable with the needle arm and you have a picture of one single set of such devices. Each drive is comprised of many sets of these in tight alignment, held in place by a spindle. The arm is held to tight tolerances and does not touch the platter but can read and write data to it by changing the magnetic state of the 'bits' on the platter. The density of the bits and the speed of the platter determine size of the drive (capacity) and it's cost.
What are the hard drive components of your computer?
The four MAJOR components of a hard drive are USB Slot, The USB Cord, The Battery, And the other stuff sorry i only know 3xxxAbove is incorrect;The five major parts of a hard-drive are:PlatterThe platter is the flat disk part of the hard drive. The platter is made up of a hard material--usually aluminum, but it varies--which is coated by material with a magnetic charge. According to "The Complete Guide to A+ Certification" by Michael Graves, the magnetic material is the part of the platter which stores the data. The magnetic charges record zeros and 1s which can be interpreted as data by the computer. Each set of magnetic particles is organized in a collection in a unit called a bit. New hard-drive technology uses thin-film metals and glass platters to increase efficiency and drive storage capacity.HeadsThe heads read and write the information to and from the drive platter. Heads are also called read-write heads. The heads write bits of magnetic information onto the platter. The closer the head is to the platter, the more efficiently it is able to read information, but a close-mounted head is more likely to have contact with a platter, potentially damaging the information. Each platter requires one head for each surface of the hard drive that needs to be read simultaneously by the head. So, if you have a two-side platter in your hard drive, you need two heads to read the sides of the platter.Actuator ArmsThe actuator arm moves the read-write head to the proper area of the platter. The head of a hard drive is mounted on the actuator arm, which moves it in order to correctly read and write the information. The actuator arm also helps keep the head an optimal distance from the hard drive platter to preserve the drive's speed and efficiency and protect the disk.Actuator MechanismThe actuator mechanism moves the actuator arm into the right place to read and write data to the hard drive platter. A controller directs the actuator to the track which is slotted for the relevant information. Most hard drive manufacturers use either a motor or a magnetic coil to move the actuator arm into place.Head ParkingHead parking is a vital part of the construction of a hard drive. Head parking maintains the small space between the head and platter, protecting the platter from suffering damage from the head. According to Graves, the head parking acts as a landing zone for the spinning platter for when the computer is powered off. Head parking can also protect the hard drive when the computer is lightly struck or jarred, but it cannot stop the hard drive from breaking when a severe blow is dealt to the hard drive, like a car accident or an angry kick to the computer.
