Consortium Roadmap Shows 100TB Hard Drives Possible By 2025
Lucas123 writes An industry consortium made up by leading hard disk drive manufacturers shows they expect the areal density of platters to reach 10 terabits per square inch by 2025, which is more than 10 times what it is today. At that density, hard disk drives could conceivably hold up to 100TB of data. Key to achieving greater bit density is Heat-Assisted Magnetic Recording (HAMR) and Bit Patterned Media Recording (BPMR). While both HAMR and BPMR will increase density, the combination of both technologies in 2021 will drive it to the 10Tbpsi level, according to the Advanced Storage Technology Consortium (ASTC).
It's called a joke. Look that up too.
Before hard disk drives, they had magnetic drums. It was a large drum that spun at a constant speed and had a separate head per track. You could read from any track, but only once the data you wanted to read rotated to be under the head for that track. Once upon a time computers used drums for main memory and core for cache.
Your idea for an arm with a head for every track is essentially a more modern drum. That and the two-armed HD are both ideas that are likely more expensive to be worth it. The head mechanism is the expensive part of the drive, so having two of them is almost as expensive as having two whole drives, so why not just have two drives?

"But it's to protect the children!" Bullshit, try shutting down the child traffickers accounts on facebook and ban advertising for foster carers for financial incentives - in fact, ban financial incentives for looking after other peoples' kids and instead try helping the families instead of making shit up about them. The best place for a child is with the family he was born into, NO EXCEPTIONS. If his entire family is dead, THEN you can talk about adoption, otherwise it's not adoption, it's trafficking.
"But it costs the artists money!" Bullshit, musicians don't make anything on CD sales (the last person who did died of a drug overdose, his name was Michael Jackson and he sold millions of records - not even the Beatles made money selling records until after they split up and Lennon got his face shot off). Musicians make money on concert footfall, and then they're paying royalties to their LABELS. Actors and filmmakers are paid in advance of publication, and their contracts stipulate no royalties - only the producer gets any royalties since it was he who stumped up the capital for the project in the first place!

The average new computer being sold today sits on a desk in an office or is a facebook machine at home. It will have in it 500GB to 1TB of storage on average ? Then whats the actual usage, 20% or less ? I have people asking me all the time, my computer is slow do I have too many pictures on it ? I look at their drive, 482GB capacity, 404GB free.
Sure there are some users who have hundreds of movies stored on their computer and businesses and datacenters who would love a drive like that but by number of computers, thats a small percentage. A majority of computers would do much better with just a SSD 1/4 the size of the HDD they currently have. A faster system overall, bootup times cut by 60%, 20-30 minutes more battery life in laptops....
