i dont know In case of magnetic storage, randomly distribuited tiny magnets present in the magnetic coating gets aligned according to the frequency and voltage levels of the information/data to be stored, thus leaving a magnetic signature of the information fed in electrical form. In case of optical storage bumps and pits are created on the medium to distinguish the variations in the signal to be stored with the help of laser beam. Depth and length of the pits corresponds to the change in information.
What else can I help you with?
What is optically storage device?
CD-R
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 is the difference between an optical and a magnetic disk?
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.
What storage device records data magnetically and is most often used for backups?
Hdd
What is the difference between backing storage devices and secondary storage devices?
there is no difference!
Does not contain a storage device?
Some devices do not contain storage devices, or do not have enough storage space needed by a particular user. Extra storage devices such as an external hard drive can be utilized.

Examples of storage devices?
THER ARE TWO TYPES OF STORAGE DEVICES: RAM(RANDOM ACCESS MEMORY DEVICE) CD WRITERAND ROM(READ ONLY MEMORY)e.g DVD ROM.Uhh no that's completely wrong there are many examples of storage devices. There is magnetic storage devices, optical storage devices, silicon storage devices, and others i cant think of.~Dawn~
What is a disk?
A disk is magnetically-writable medium that you put in a disk drive inside a computer (PC). A disc, on the other hand, is optically writable (such as a CD or DVD). The easy way to remember which term to use is the "C is for CD."
Are hard drives considered volatile storage devices?
No, they are permanent storage devices, only RAM is volatile storage device.
Some storage devices?
It's a storage that is attached internally in the device's box.
Name the 3 types of storage devices?
