Sib nqus daim kab xev cov ntaub ntawv cia yog ib qhov system rau khaws cia cov ntaub ntawv digital ntawm daim kab xev sib nqus siv cov ntaub ntawv digital. Niaj hnub daim kab xev sib nqus yog feem ntau ntim rau hauv cartridges thiab cassettes. Cov cuab yeej ua ntawv sau lossis nyeem ntawv cov ntaub ntawv yog a daim kab xev tsav. Autoloaders thiab daim kab xev cov tsev qiv ntawv automate cartridgehandling.
Tsis tas li ntawd, dab tsi yog kev siv daim kab xev nplaum?
Sib nqus daim kab xev yog qhov ntev thiab nqaim strip ntawm yas uas nyias Sib nqus cov khoom yog coated rau. Yuav luag txhua qhov kaw daim kab xev yog hom no, txawm siv rau kev kaw suab lossis video lossis computer cov ntaub ntawv khaws cia. Sib nqus daim kab xev kaw tseg siv daim kab xev sib nqus uas txav ntawm arecording taub hau.
Qhov thib ob, ntau npaum li cas cov ntaub ntawv tuaj yeem khaws cov ntaub nplaum sib nqus? Cov kab hlau nplaum tuaj yeem khaws cia mus txog ib terabyte ntawm uncompressed cov ntaub ntawv -as ntau raws li ua tau yuav khaws cia rau lub hard disk. Sib nqus daim kab xev siv 'serial access' los nrhiav ib qho ntawm cov ntaub ntawv.
Nyob rau hauv kev hwm rau qhov no, dab tsi yog magnetic daim kab xev Yuav ua li cas khaws cov ntaub ntawv rau nws?
Sib nqus daim kab xev drives khw cov ntaub ntawv ntawm daim kab xev sib nqus siv cov ntaub ntawv digital. Cov daim kab xev ib txwm khaws cia ntawm daim cartridges lossis cassettes, tab sis rau drivesthat yog siv raws li cov ntaub ntawv khaws cia daim kab xev backups, cov daim kab xev feem ntau yog mob ntawm reels.
Cov kab xev cia ua haujlwm li cas?
Sib nqus daim kab xev uas zoo ib yam li cov suab paj nruag daim kab xev , muaj ib txheej magnetized ntawm ib daim nyias nyias uas cov ntaub ntawv sau rau. Tsis zoo li dynamic thiab random khaws cia nruab nrab xws li hard disks thiab flash drives, a daim kab xev tsav ua haujlwm siv indexing andsequential-access.
