Faster access time(uses data bus directly and not through any controller) and no moving parts
A big advantage of a machineâ??s main memory over Magnetic Disk Storage is that it has a greater speed in processing data. Another advantage of it is the durability of it because there are no moving parts that might break.
Disk storage is nonvolatile, meaning data is not lost when power is turned off. Also, disk storage is by far cheaper per unit compared to main memory.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.

Hard Disk
Magnetic disk.
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.
Floppy disks use magnetic disk to store the data.
A floppy disk is an old type of removable, computer memory storage.
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)
it is the primary storage unit of a computer
Random Access Memory, as verses Sequential Access Memory (delay lines, magnetic tape, magnetic drum, magnetic disk, etc.)
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.
