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

Tsis tas li ntawd, cov ntaub ntawv khaws cia thiab nyeem los ntawm lub hard disk li cas?

A magnetic disk tsav muaj ntau lub platters ( disks ) coated hauv a Sib nqus khoom. Lawv tig ntawm ib ncig ntawm 7200 rpm. Cov data yog encoded rau hauv cov khoom thiab sau rau saum npoo raws li cov kev hloov pauv hauv cov kev taw qhia ntawm magnetization. Cov cov ntaub ntawv yog nyeem los ntawm kev txheeb xyuas cov kev hloov hauv kev coj ua.

Ib yam li ntawd, puas yog lub hard drive ib qho khoom siv sib nqus? A hard disk tsav ( HDD ), hard disk , hard drive , los yog kho disk yog cov ntaub ntawv electro-mechanical khoom cia uas siv sib nqus cia khaws thiab khaws cov ntaub ntawv digital siv ib lossis ntau qhov nruj nrawm nrawm disks (platters) coated nrog Sib nqus khoom.

Sib piv, dab tsi yog cov khoom siv sib nqus thiab kho qhov muag?

Optical Storage Devices : Optical cia khoom yog tiaj, round disks uas tig ncig nws qhov chaw. Qhov txawv nrog magnetic cia khoom yog in optical cia khoom LASER teeb yog siv los nyeem thiab sau cov ntaub ntawv hauv disks. Piv txwv li CD, DVD thiab lwm yam.

Cov khoom siv sib nqus cia ua haujlwm li cas?

Ib yam li lub hard drive, lub xov xwm siv nyob rau hauv tshem tau Sib nqus - cov khoom siv cia yog coated nrog hlau oxide. Thaum cov ntaub ntawv raug nyeem los ntawm tus tsav, lub taub hau nyeem rub tawm qhov sib txawv Sib nqus teb hla qhov sib txawv, tsim kom muaj qhov sib txawv Sib nqus teb nyob rau hauv lub tub ntxhais thiab yog li ntawd ib tug teeb liab nyob rau hauv lub kauj.
