Pamsonkhano wopereka malipoti wa kotala wa Seagate, wamkulu wa kampaniyo adavomereza kuti kubweretsa ma hard drive a 16 TB kudayamba kumapeto kwa Marichi, komwe tsopano akuyesedwa ndi othandizana nawo komanso makasitomala a wopanga uyu. Magalimoto omwe amagwiritsa ntchito ukadaulo wa laser-assisted magnetic wafer heat (HAMR), monga mkulu wa Seagate adanenera, amawoneka bwino ndi makasitomala: "Amangogwira ntchito." Koma zaka zingapo zapitazo panali kuyankhula zaukadaulo wonse wa HAMR za kudalirika kwake kosakwanira, ndipo omwe akupikisana nawo a Seagate sanachedwe kutengera. Ziyenera kuganiziridwa, komabe, kuti Seagate sinakonzekere kugulitsa ma hard drive otere, ndipo kugwiritsa ntchito malonda aukadaulo wa HAMR kudzayamba pokhapokha atatulutsa ma drive 20 TB.
Ngati muyang'ana, Toshiba kwa nthawi yayitali adayang'ana kuonjezera chiwerengero cha mbale za maginito mu hard drive case, ndipo sanafulumire kuyambitsa zatsopano monga "matayilo" omwewo (SMR). Chotsatira chake, chinayandikira malire a 16 TB ndi mapangidwe apamwamba a maginito a maginito ndipo pokhapokha akafika pamtunda wa 18 TB adzayamba kugwiritsa ntchito SMR, ngakhale kuti amalolanso kuphatikiza kwa mbale wamba ndi luso la MAMR, lomwe limaphatikizapo. kulimbikitsa ma TV pogwiritsa ntchito ma microwave. Koma kwa Toshiba, kuyika mbale zisanu ndi zinayi za maginito mu 3,5 β³ form factor kesi ndi gawo lomwe ladutsa, ndipo kampaniyo ikuganiza zopanga ma drive okhala ndi mbale khumi zamaginito.
Chilakolako cha Toshiba chokulitsa kuchuluka kwa mbale za maginito zomwe zidakhala ngati chandamale chonyozedwa ndi Western Digital Corporation, omwe oyimilira awo pamsonkhano wachigawo wa kotala adanena kuti 16 TB hard drive ya mbale zisanu ndi zitatu zamaginito zokhala ndi ukadaulo wa MAMR zitha kukhala zotsika mtengo kupanga kuposa omwe akupikisana nawo '. mankhwala. WDC idziwa njira ya "matayilo" potulutsa ma drive 18 TB, omwe adzatulutsidwa kumapeto kwa chaka chino. Popanga ma drive opitilira 20 TB m'zaka khumi zikubwerazi, WDC idzagwiritsa ntchito luso la MAMR lokha, komanso mayunitsi awiri odziyimira pawokha (ma actuators).
Yankho laposachedwa likugwiritsidwanso ntchito ndi Seagate, ndipo pa kayendetsedwe ka msonkhano wa kotala adalongosola kuti kusintha kwa mitu iwiri yamutu kungapereke kuwonjezeka kwakukulu kwa liwiro la kutumiza deta, zomwe ziri zofunika, mwachitsanzo, ntchito yaikulu ndi kanema. Mu April kampani mtundu wopangidwa kale wa 16 TB hard drive yokhala ndi ukadaulo wa HAMR; kubweretsa zitsanzo zamagalimoto otere kudayamba kumapeto kwa Marichi, koma sizipanga. M'chaka, malinga ndi oimira Seagate, mitundu 16 ya TB idzakhala gwero lalikulu la ndalama mu gawo la seva. Mitundu yambiri yazogulitsa za voliyumu iyi iphatikiza kujambula kwa "perpendicular" ndi TDMR pama mbale asanu ndi anayi; Seagate isinthira ku "matayilo" kujambula pokha popanga ma drive 18 TB, koma azichita popanda zanzeru ngati HAMR.
M'chaka cha kalendala cha 2020, Seagate idzayambitsa ma hard drive a 20 TB okhala ndi ukadaulo wa HAMR. Popita nthawi, zipangitsa kuti zitheke kupanga ma hard drive okhala ndi mphamvu yopitilira 40 TB, koma onse omwe akupikisana nawo a Seagate amalonjeza pafupifupi chinthu chomwecho, pogwiritsa ntchito ukadaulo wosiyana pang'ono, kotero kulimbana pamsika wamagalimoto kumalonjeza kukhala kwakukulu. .
