Vatsvagiri paYunivhesiti yeSouthampton vakagadzira nzira yekukurumidza yekunyora laser uye kushandisa simba kugadzira yakakwirira-density nanostructures mu silica girazi. Zvimiro zvidiki izvi inogona kushandiswa kune optical data kuchengetedza refu-refu shanu-dimensional (5D), kupfuura 10.000 times deser kupfuura Blue-Ray optical disc kuchengetedza tekinoroji.
Rudzi urwu rwekuchengetedza data runoshandisa mitsara mitatu nanoscale points pagirazi dhisiki. Saizi, kutarisisa uye chinzvimbo (muzvikamu zvitatu) zvemapoinzi zvinopa "zviyero" zvishanu zvinoshandiswa kukodha data.
Sekureva kwevaongorori. dhisiki re5D rinogona kuverengeka mushure memakore 13.8 bhiriyoni, asi zvingava zvinoshamisa kana mumwe munhu akanga achiri pedyo kuti aiverenge panguva iyoyo. Nenguva pfupi, 5D optical media inogonawo kurarama mushure mekupisa kusvika 1.000 degrees Celsius.
Unyanzvi yakagadzirwa nemuongorori wePhD Yuhao Lei anoshandisa femtosecond laser yakakwirira yekudzokorora mwero. Maitiro acho anotanga nembeu yembeu inogadzira nano vacuum, asi kukurumidza kupuruzira hakudi chaizvo kunyora data. Iwo anodzokororwa asina kusimba pulses anoshandisa chiitiko chinozivikanwa sepadyo-munda kusimudzira kuveza nanostructures nenzira yakapfava. Vatsvakurudzi vakaongorora laser pulses pamatanho emagetsi akasiyana uye vakawana nhanho inomhanyisa kunyora pasina kukuvadza silica girazi disc.
Chidzidzo chinoshuma huwandu hwe data hunosvika miriyoni imwe chete pasekondi, asi chidimbu chega chega chinoda ma voxel akati wandei mu5D optical system. Izvi zvakaenzana nehuwandu hwe data hunosvika 230 kilobytes pasekondi. Panguva ino, zvinokwanisika kuzadza imwe yedhisiki, iyo inokwana inofungidzirwa pa500 TB. Zvinotora inenge mwedzi miviri kunyora yakawanda yakadaro data, mushure mokunge yaisagona kuchinjwa.
"Vanhu nemasangano vari kugadzira maseti edata akakura, zvichiita kuti padiwe nzira dzakasimba dzekuchengetedza data zvine huwandu hwakanyanya, kushandiswa kwemagetsi kushoma, uye hupenyu hurefu," akadaro muongorori Yuhao Lei, wekuYunivhesiti yeSouthampton, UK. "Kunyange masystem-based system ari kunyanya kugadzirirwa data yenguva pfupi, isu tinotenda kuti 5D dhata chengetedzo mugirazi inogona kubatsira mukuchengetedza data kwenguva refu kudura renyika, mamuseum, maraibhurari, kana masangano akazvimirira." akawedzera.
Kunyange zvazvo 5D optical data kuchengetedza pane zvinhu zvakajeka zvakaratidzwa munguva yakapfuura, zvakaratidzwa kuti zvakaoma kunyora data nekukurumidza uye nekuwanda kwakakwana kune chaiyo nyika maapplication. Kukunda chipingamupinyi ichi, vaongorori vakashandisa yakakwira yekudzokorora mwero femtosecond laser kugadzira matsime madiki ane yakasarudzika nanolamella-yakafanana chimiro inoyera 500 x 50 nanometers imwe neimwe.
Panzvimbo pekushandisa femtosecond laser kunyora zvakananga pagirazi, vaongorori vakaisa mwenje kuti ibudise chiitiko chemaziso chinozivikanwa sepadhuze-munda kuwedzera, umo nanolamella-yakafanana dhizaini inogadzirwa neashoma mashoma pulses. nano vacuum inogadzirwa nea single pulse micro explosion. Kushandiswa kwepadhuze-munda kusimudzira kugadzira nanostructures kwakaderedza kukuvara kwemafuta kwave kunetsa kune dzimwe nzira uchishandisa yakakwirira-frequency inodzokorora lasers.
Sezvo nanostructures iri anisotropic, inogadzira birefringence iyo inogona kuratidzwa nekutarisa kweanononoka axis yechiedza (4th dimension, inoenderana nekutarisa kweiyo nano-laminate chimiro) uye kunonoka simba (5th dimension, inotsanangurwa nehukuru hwenanostructure. ) Kana data yakanyorwa pagirazi, kutaridzika kweiyo inononoka axis uye kusimba kwekunonoka kunogona kudzorwa nepolarization uye kusimba kwechiedza, zvichiteerana.
"Iyi nzira nyowani inovandudza kukurumidza kwekunyora data kusvika padanho rinoshanda, kuitira kuti tikwanise kunyora makumi egigabytes yedata munguva inonzwisisika," akadaro Lei. Yakanyanya kurongeka chaiyo nanostructures inobvumira hukuru hwe data, sezvo mamwe ma voxels anogona kunyorwa muvhoriyamu yeyuniti. Mukuwedzera, kushandiswa kwechiedza chepulsed kunoderedza simba rinodiwa kunyora. «
Vatsvakurudzi vakashandisa nzira yavo itsva yekunyora 5 gigabytes ye data data kune girazi disk. silica saizi yeyakajairwa compact disc, nekunyatsoverenga kweinenge 100%. Voxel yega yega yaive nemabhiti mana eruzivo, uye ese mavhokisi aienderana nemavara echinyorwa. Nehuwandu hwekunyora hunopihwa nenzira, dhisiki yaigona kubata mazana mashanu eterabytes edata. Nekuvandudzwa kwehurongwa kunobvumira kunyora kwakafanana, vaongorori vanoti zvinofanirwa kuve zvichikwanisika kunyora huwandu uhu hwedata mumazuva angangoita makumi matanhatu.
Nehurongwa hwazvino, isu tine kugona kuchengetedza terabytes yedata, inogona kushandiswa, somuenzaniso, kuchengetedza mashoko eDNA omunhu ari kushanda kuti awedzere kukurumidza kunyora kwenzira yake uye kuita kuti michina yacho ishandiswe kunze kwerabhoritari. Izvo zvichave zvakare zvakafanira kuvandudza nzira dzinokurumidza dzekuverenga data kune inoshanda data warehousing application.
