Western Digital, along with Seagate, Toshiba, and Hitachi are working on the next step in increasing the storage density of platter based drives while HAMR is still in the works. They will be adding overlapping tracks to their platters, which they are referring to as shingles (as in the roof, not the pox). There will be two types implemented, with the first type having the shingling hidden to ensure compatibility with existing applications which might take exception to overlapping data tracks. Type two will not hide its light under a bushel and will require applications to be aware of the shingling and hopefully take full advantage of the new type of magnetic recording. According to the presentation that The Register attended we will see shingles in the near future, with HAMR due in 2016.
"Over the coming years the remaining players will be pushing traditional technology to its limits to extend the life of hard disk technology. While the industry is pretty much standardised on perpendicular magnetic recording (PMR) at present, in a couple of years there will be more fundamental hard drive technologies co-existing in the market than there are hard drive vendors."

Tagged: Hard Drive, Areal Density, 1TB Platter
In an amazing feat of data density, Seagate has once again made a leap to the next level of storage technology unveiling 1 Terabyte per platter drives. WIth an areal density of 625 Gigabytes per square inch, Seagate claims the new drives are capable of storing “virtually countless hours of digital music,” and “1,500 video games.”
The move to 1TB per platter drives is an especially important step for high capacity drives. Current 1TB+ drives are using two 500 GB platters, while current 3TB drives are using either four 750 GB platters in the form of the WD Caviar Green 3 TB that PC Perspective has reviewed here, or the five 600 GB platters. With Seagate’s new technology, they will be able to cut the number of platters in their highest capacity 3 TB drives almost in half. By moving from five platters to three, their drives will run cooler, faster, and with less power draw. Improved areal density also reduces the number of moving parts, and thus decreases the points of failure, even with the inclusion of newer and more sensitive read heads.
The place in the market where this new technology will make the most noticeable difference is in the mobile segment. With just a single platter, mobile users will have close to 1.5 terabytes of internal storage in a two platter drive, or 750 GB in a one platter drive while using less power and being capable of faster reads. This means that road warriors will be able to keep more of their files with them without reducing battery life compared to the current crop of mobile hard drives.
Unfortunately, mobile users will have to wait, as Seagate has only announced 3.5” desktop and external drives. These drives will be branded under both the Seagate Barracuda XT and GoFlex lines respectively.
For desktop users, they can currently expect capacities ranging from 1TB to 3TB drives. In a RAID array, these new lower power and potentially faster drives would make for a great addition to an HD video editing rig. Call me crazy, but I’m going to hold onto my old school 320 GB Seagate drives until I can jump straight to 4 TB. So, where’s my 4 platter, 4TB drive Seagate?
Are you excited about this new platter technology? What would you do with 3 terabytes of storage?
