Qhov chaw ntawm disks thiab Sib nqus tapes yog coated nrog ntau lab ntawm cov hlau me me kom cov ntaub ntawv tuaj yeem ua tau khaws cia ntawm lawv. Cov ntawv sau / nyeem lub taub hau ntawm disk tsav los yog daim kab xev tsav muaj electromagnets uas tsim Sib nqus teb nyob rau hauv lub hlau ntawm lub khaws cia nruab nrab thaum lub taub hau hla lub disk lossis daim kab xev.

Tsis tas li ntawd, cov khoom sib nqus ua haujlwm li cas?

Sib nqus cia los yog sib nqus kaw yog cov khaws cia ntawm cov ntaub ntawv nyob rau hauv ib tug magnetized nruab nrab. Sib nqus cia siv cov qauv sib txawv ntawm magnetisation hauv cov khoom siv magnetisable los khaws cov ntaub ntawv thiab yog ib daim ntawv uas tsis yog-volatile nco . Cov ntaub ntawv nkag mus siv ib lossis ntau dua nyeem / sau taub hau.

Tsis tas li ntawd, cov cuab yeej sib nqus yog dab tsi? Sib nqus cia yog ib txoj hauv kev pheej yig tshaj los khaws cov ntaub ntawv ntau. Sib nqus cia siv ob hom ntawm Sib nqus polarities los sawv cev rau cov ntaub ntawv binary uas muaj zeros thiab ib qho. Feem ntau siv cov khoom siv uas siv sib nqus cia suav nrog Sib nqus daim kab xev, floppy disks thiab hard-disk drives.

Ib yam li ntawd, lub magnetic disk khaws cov ntaub ntawv li cas?

A Sib nqus disk yog a khaws cia ntaus ntawv uas siv cov txheej txheem magnetization los sau, rov sau dua thiab nkag mus cov ntaub ntawv . Nws yog them nrog a Sib nqus txheej thiab khaws cov ntaub ntawv nyob rau hauv daim ntawv ntawm lem, me ntsis thiab sectors. Nyuaj disks , zip disks thiab floppy disks yog cov piv txwv ntawm magnetic disks.

Yuav txhim khu kev qha magnetic cia?

Hauv cov ntsiab lus no, Sib nqus tapes yog tam sim no nyob ib tug thib ob hluas hluas. Qhov kev daws teeb meem no tau raug pov thawj thiab ruaj khov - tau ntau xyoo nws tau siv rau cov ntaub ntawv khaws cia thiab suav tias yog kev nyab xeeb thiab tsis tshua muaj neeg ntseeg tau . Nyob rau hauv lub sij hawm ntawm nias kom zoo dua hardware tsis, tshwj xeeb tshaj yog ceev, tapes tau kwv yees yuav ploj mus sai sai.
