In the read write head mechanism of a floppy drive how many heads are attached at the end of an actuator arm that freely moves over the surface of the disk?
two
Does the read write heads on a hard disk drive actually touch the surface of the disk?
no, the head not touching the surface of the hard disk. If it touch the great chance of data may be lost. only the head of floppy disk is touch the surface of the disk.
What do you call the device that reads information from a disk and writes information to a disk?
In the drive mechanism the part that does this is the head assembly.
What are the characteristics of disk operating system?
1 ) Head Motion. 2) Disk Portability. 3)Sides . 4)Platters. 5)Head Mechanism.
What is the term used to describe what happens when the read-write head of a hard disk touches the surface of the disk platter?
HDI - Head to Disk Interference.
What is the device that reads and records information on disks?
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
What is Head actuator mechanism in harddisk?
a head actuator moves a gang of read/write head arm across the surface of the platter with critical precision
Where does hard disk information stored?
In magnetic particles on the hard drive disk surface. The drive head reads the magnetic particles and interprets if they are ones or zeros. The head doesn't touch the disk surface but resides about .00005 thousands away from the surface. Just opening the drive housing in an unclean environment can render the drive unusable. It also voids the warranty
What does the top and bottom of each disk of a magnetic hard drive have an that moves across the disk surface as all the disks rotate on a spindle?
read/write head
What is the hard disk?
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
How the working of floppy disk drive differ from hard disk drive?
The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
What is an electronic electrical and mechanical parts of the computer?
electronic - microprocessor, RAM, ROM, etc.electrical - power supplymechanical - hard disk head arm mechanism, fan blades
