Tsis ntev los no,Microsoft Kev Tshawb Fawbtshaj tawm qhov nthuav heev "silica project." Lub phiaj xwm tsom mus rau kev txhim kho ib puag ncig tus phooj ywg los khaws cov ntaub ntawv loj hauv iav daim hlau siv ultrafast lasers - ua kom nws tuaj yeem khaws "cov ntawv theej" ntawm cov suab paj nruag, tsos, thiab ntau dua hauv iav.
Dab tsi tseem ceeb tshaj yog tias thaum cov ntaub ntawv tau sau tiav, cov ntaub ntawv hauv silicon iav yuav nyob twj ywm tsis hloov pauv rau ntau txhiab mus rau kaum txhiab xyoo thiab tuaj yeem tiv taus hluav taws xob pulses thiab huab cua kub.
Txhawm rau muab nws yooj yim, Microsoft tau ua 3-inch-ntev square "hard drives" tawm ntawm quartz iav, txhua tus tuaj yeem khaws 100GB ntawm cov ntaub ntawv thiab txog 20,000 nkauj.
Txoj haujlwm no yog kev koom tes ntawm Microsoft thiab txhawb nqa kev koom tes nrog pab pawg neeg lag luam Elire, nrog rau ob tog vam tias yuav pom cov ntaub ntawv khaws cia ntau dua uas yuav ua rau cov ntaub ntawv hauv iav "tsis tawg."
Cov txheej txheem khaws cia iav suav nrog kev sau ntawv siv ultra-ceev femtosecond lasers, nyeem los ntawm lub khoos phis tawj tswj hwm lub khoos phis tawj, kev txiav txim siab thiab sau ntawv, thiab thaum kawg khaws cia rau hauv "tsev qiv ntawv." Qhov tseem ceeb, qhov "qib qiv" no ua haujlwm dhau los thiab tsis siv hluav taws xob, uas muaj peev xwm txo qis cov pa roj carbon emissions cuam tshuam nrog cov ntaub ntawv mus ntev.
Project Silica tsim ib daim ntawv ruaj khov ntawm cov ntaub ntawv ntau tshaj li qhov txwv-lub neej sib nqus cia, uas raug kev txom nyem los ntawm kev sib tw tsis tu ncua, nce kev siv hluav taws xob, thiab cov nqi khiav lag luam.
Ant Rowstron, tus kws tshaj lij ntawm silicon dioxide project engineer, tau hais tias: "Lub neej kev pab cuam ntawm magnetic technology yog txwv. Lub hard drive yuav siv tau li ntawm 5-10 xyoo. Thaum lub neej voj voog dhau lawm, koj yuav tsum luam nws dua thiab txuag nws mus rau ib tiam tshiab ntawm kev tshaj tawm. "Honestly, nws yog cumbersome thiab unsustainable thaum koj xav txog tag nrho cov zog thiab cov kev pab cuam peb tab tom siv."
Kev khaws cia lub neej yav tom ntej ntawm lub ntiaj teb suab paj nruag los ntawm iav
Sustainability-focused venture capital pab pawg Elire tam sim no tau dhau los ua lub tuam txhab tshiab los koom tes nrog Microsoft Research Project Silica pab pawg, koom nrog cov nyiam CMR Surgical uas yog siv iav cov ntaub ntawv khaws cia los hloov kho neeg hlau txoj kev phais yav tom ntej.
Elire yuav siv thev naus laus zis ntawm Global Music Vault hauv Svalbard, Norway, qhov chaw me me ntawm iav tuaj yeem tuav tau ob peb terabytes ntawm cov ntaub ntawv, txaus khaws cia kwv yees li 1.75 lab nkauj lossis 13 xyoo suab paj nruag. Qhov no yog ib kauj ruam tseem ceeb rau kev ruaj ntseg cov ntaub ntawv.
Microsoft tau taw qhia tias txawm hais tias iav cia tseem tsis tau npaj txhij rau kev nce qib loj, nws tau suav tias yog qhov kev cog lus kev lag luam ruaj khov vim tias nws cov kav ntev thiab tus nqi siv tau zoo, thiab cov nqi tu tsis tu ncua yuav yog "tsawg kawg". Tsuas khaws cov ntaub ntawv iav no rau hauv lub tsev qiv ntawv uas yuav tsum tsis muaj hluav taws xob. Thaum xav tau, tus neeg hlau nce mus rau lub txee kom khaws nws rau kev ua haujlwm tom ntej.
Lub peev xwm ntawm cov ntaub ntawv kho qhov muag yog dab tsi?
Nyob ntawm txoj kev khaws cia, txoj kev khaws cia tuaj yeem yog xov xwm electromagnetic, optical media, lossis lwm yam xov xwm. Cov txheej txheem kho qhov muag kho qhov muag siv cov discs zoo li Blu-duab tshav uas muaj txheej txheej ntawm cov khoom cuam tshuam. Optical drives siv lasers los tsim cov pits uas tsis yog-reflective nyob rau hauv cov coatings uas nyob ib sab, uas tau kuaj pom los ntawm lub laser uas nyeem cov pits. Thaum kuaj pom cov qauv ntawm qhov pits thiab qhov chaw tsis muaj qhov cuam tshuam tau pom, cov ntaub ntawv khaws cia tuaj yeem nkag mus.
Txawm li cas los xij, nyob rau hauv cov ntsiab lus ntawm kev loj hlob ntawm cov ntaub ntawv hauv Is Taws Nem, kev tshaj xov xwm, thiab kev siv huab cua, qhov kev thov rau ultra-high-density optical data storage tau nce siab - cov ntaub ntawv khaws cia ceev yuav tsum tau kov yeej lub bottlenecks ntawm tsoos magnetic hard drives. los yog tapes thiab solid-state drives (SSD) cia. thiab cov kev daws teeb meem rau cov ntaub ntawv mus sij hawm ntev.
Nws yog dav ntseeg tias optical technology yog tus yuam sij rau kev txhim kho lub peev xwm cia ntawm cov ntaub ntawv loj. Lub tswv yim saum toj no ntawm kev siv iav rau cov ntaub ntawv khaws cia tuaj yeem taug qab rov qab mus rau xyoo pua 19th. Tom qab ua tib zoo txhim kho thiab txhim kho thev naus laus zis, ntau yam teeb meem tau dhau los ntawm ib qho.
Tsis tas li ntawd, piv nrog cov cuab yeej kho qhov muag tam sim no, ib qho ntawm qhov zoo tshaj plaws ntawm cov ntaub ntawv kho qhov muag yog tias nws tuaj yeem ua tiav cov ntaub ntawv ntau qhov chaw cia.
Raws li lub npe qhia, cov ntaub ntawv ntau qhov chaw khaws cia feem ntau sau thiab nyeem cov ntaub ntawv hauv cov qauv nrog ntau tshaj peb qhov ntev (xws li ntau txheej optical discs, phaib, muaju, lossis lub voos xwmfab). Kev sau ntawv thiab nyeem cov ntaub ntawv feem ntau yog ua tiav los ntawm kev tsom ib lossis ntau lub teeb laser rau hauv qhov nruab nrab peb sab. Vim lub volumetric xwm ntawm qhov nruab nrab cia, lub laser yuav tsum dhau los ntawm cov ntsiab lus ntxiv ua ntej sau los yog nyeem cov fiducials yuav tsum tau. Qhov no txhais tau hais tias ob qho tib si sau thiab nyeem cov haujlwm feem ntau yuav tsum tsis yog-linear kom tsuas yog ib qho chaw hauv zos ua tiav ntawm lub sijhawm.
Niaj hnub no, 5D optical data storage technology tau raug pov thawj - optical discs siv cov cuab yeej no tuaj yeem khaws cia txog 360Tb cov ntaub ntawv thiab tuaj yeem khaws cia rau ntau txhiab xyoo. Xyoo 1996, cov kws tshawb fawb thawj zaug tau thov thiab ua kom pom kev siv femtosecond lasers los sau thiab khaws cov ntaub ntawv. Cov thev naus laus zis no tau nthuav tawm thawj zaug hauv xyoo 2010 los ntawm Kazuyuki Hirao lub chaw kuaj mob ntawm Kyoto University thiab tsim ntxiv los ntawm Peter Kazansky pawg tshawb fawb ntawm University of Southampton's Optoelectronics Research Center. Tsis tas li ntawd, Hitachi thiab Microsoft kuj tau kawm txog iav-raws li optical cia technology, tom kawg lub project hu ua "Project Silica." Thoob plaws ntiaj teb, cov players loj hauv kev lag luam kho qhov muag suav nrog Sony, Western Digital, Samsung Electronics, IBM, Toshiba, thiab Fujitsu.
5D kho qhov muag cov ntaub ntawv khaws cia feem ntau yog ua raws li kev sim nanostructured iav uas khaws cov ntaub ntawv tsis yog los ntawm kev sau cov ntaub ntawv hauv peb qhov chaw tab sis kuj los ntawm ob qhov tsis muaj feem cuam tshuam nrog birefringence, uas tau txiav txim siab los ntawm tsom iav. Polarization thiab siv tswj femtosecond laser hauv nruab nrab. Qhov loj me, kev taw qhia, thiab peb-dimensional txoj hauj lwm ntawm nanostructure ua rau tsib qhov loj uas tau hais los saum no.
Txawm li cas los xij, txhawm rau txhim kho kev lag luam daim ntawv thov kev cia siab ntawm cov thev naus laus zis no, cov ntaub ntawv nyeem ceev kuj yuav tsum tau txhim kho. Tsis tas li ntawd, nws daim ntawv thov yuav raug txwv vim qhov yuav tsum tau muaj lub zog laser system thiab tsis muaj cov ntaub ntawv rov sau dua.
Cov ntaub ntawv kho qhov muag kuj tseem muaj peev xwm ua tau rau multilevel encoding technology, uas tuaj yeem ua kom muaj peev xwm khaws cia ntau ntxiv los ntawm kev sau ntau cov khoom hauv ib qho taw tes uas siv cov teeb liab sib txawv sib txawv. Ntau cov ntaub ntawv khaws cia kuj tseem tuaj yeem nyeem tawm ntau cov khoom ib txhij, yog li ua kom cov ntaub ntawv nyeem tawm tus nqi, uas tseem ceeb heev rau cov ntaub ntawv loj.
Hauv kev siv thev naus laus zis tshiab los ntawm University of South Australia thiab University of New South Wales, cov kws tshawb fawb tuaj yeem siv cov khoom tshwj xeeb ntawm inorganic phosphors los khaws cov ntaub ntawv. Txoj hauv kev no muaj peev xwm rov sau dua thiab siv cov lasers qis. Tsis tas li ntawd, thev naus laus zis tsis tas yuav muaj qhov kub thiab txias txias thiab tuaj yeem hloov qhov kub ntawm qhov kub ntawm chav tsev, ua rau nws siv tau ntau dua.
