What is a “shingled” hard drive?

Seagate is releasing a new line of HDDs. The main selling points are that they offer an impressive amount of storage for the price; an 8TB drive will sell for $260. Seagate is talking about these new “Shingled Magnetic Recording” drives, but what does that actually mean? Is this a new method of HDD construction, just a marketing phrase, or what?

Singled Magnetic Recording (via Wikipedia):
“...a technique to increase capacity used in hard disk drive magnetic storage. Conventional hard drives record data by writing non-overlapping magnetic tracks parallel to each other, while shingled recording writes new tracks that overlap part of the previously written magnetic track, leaving the previous track thinner, allowing for higher track density. The tracks partially overlap similar to roof shingles.”

Seagate’s YouTube video about these drive is actually pretty neat. These drives are interesting, the only real drawback is that they are slow. If you are interested: http://youtu.be/3UFUfv9n420
