In 2014, Seagate plans to release its 6TB drives with SMR (Shingle
Magnetic Recording) technology – SMR shows potential for producing 8 – 10TB
drives.
In SMRs, the write head magnetises bits in tracks, which are as wide as
those in the perpendicular technology but here they overlap one another like
shingles on a roof. The reading head, which is smaller than the write head,
traces bits only from the narrow space, thus achieving higher data density and
higher drive capacity.
