Magnetic storage is used on hard drives and floppy disks.
Sectors of the disk are charged magnetically and are easily changed later.
Optical storage uses a laser to read data.
On a cd/dvd, the laser picks up tiny marks made starting in the center
and rotating outward.

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.
Is CD-r disk a hard disk?
No, it is an optical disc. A hard disk is defined as a device that stores data on spinning magnetic platters. Although a CD is 'hard' (rigid) as opposed to the flexible inside of a floppy disk, that does not classify it as a hard disk.
What do you call the subdivision of a track on magnetic disk or optical disk?
A sector
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.
Are magnetic disk and optical disk secondary storage devices?
Yes both are secondary storage devices. Primary storage devices include RAM & ROM. Secondary storage devices include magnetic disks like hard disks and cds(optical disks)
What type of media is a hard disk?
optical
What is the correct spelling for computer disc drive?
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".
Is a CD-ROM an optical or solid state or magnetic?
A compact disk (CD) is an optical storage device.
What are the limitations of optical disk?
(a)- it is a read-only storage medium. Data once recorded, cannot be erased, and hence the optical disk cannot be reused. (b)- thd data access speed for optical disk is slower than magnetic disks; (c)- optical disk require a more complicated drive mechanism that magnetic disk.
Use magnetic particles to store items on a disk surface?
magnetic disk
What is a mechanism that holds spin read and writes magnetic or optical disks?
disk derive
Why magnetic media is suitable for multimedia applicatiion?
Magnetic media like a hard disk drives are fairly fast so it is suitable for multimedia applications. Optical media like DVDs and CDs are much slower.
