What else can I help you with?
Do magnetic disks use magnetic particles to store items such as data instructions and information on a disks surface?
True.
What uses magnetic particles to store items on a disks surface?
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
Magnetic disks use magnetic particles to store items such as data instructions and information on a disk's surface True or false?
true
Which process converts binary information into patterns of magnetic flux on a hard disks surface?
The process that converts binary information into patterns of magnetic flux on a hard disk's surface is called magnetic recording. This involves encoding binary data (0s and 1s) into magnetic fields, which are created by the read/write head of the hard drive. The head alters the magnetic orientation of tiny regions on the disk's surface, representing the stored data as changes in magnetic flux. When data is read, the changes in magnetic orientation are detected and translated back into binary information.
Are CDs and DVDs magnetic disks?
No. A CD is a type of optical media. An example of magnetic media would be tape (eg. VHS and cassette)
What is the surface charge density on the disks?
The surface charge density on the disks is the amount of electric charge per unit area on the surface of the disks.
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.
How are magnetic disks used as storage media?
Audio
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
Example of a dynamic memory unit?
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
Floppy disks use this type of storage media?
Magnetic
Why hard disc are magnetize with iron oxide?
Hard-disks are coated with iron oxide because it reacts to a magnetic source ! The information on a hard-disk is read and written by a magnetic 'head' which scans across the surface as the disk rotates.
