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.
Do Magnetic storage devices use disks that are coated with magnetically sensitive material and use sectors to read information by transforming electrical impulses into a varying magnetic?
Yes, magnetic storage devices use disks coated with magnetically sensitive material, such as magnetic oxides. These disks are divided into sectors, which allows data to be organized and accessed efficiently. Information is read by transforming electrical impulses into varying magnetic fields, enabling the storage and retrieval of data. This process is fundamental to the operation of devices like hard disk drives (HDDs).
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
How are magnetic disks used as storage media?
Audio
In a magnetic disk drive a special device is called what that reads and writes data to a disks surface?
In a magnetic disk drive, the special device that reads and writes data to the disk's surface is called a read/write head. This head operates at a very small distance from the disk platter, utilizing magnetic fields to detect and alter the magnetic orientation of the disk surface, thereby enabling data retrieval and storage.
Example of a dynamic memory unit?
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
