Source : CDR InfoCouple of hours before the beginning of the 8th Perpendicular Magnetic Recording Conference (PMRC 2007 October 15-17, 2007) to take place at the Tokyo International Forum in Japan, Hitachi announced to have miniaturized recording heads by more than a factor of two, opening the way to a huge increase in HD recording density. Hitachi expects to introduce its perpendicular-to-the-plane giant magnetoresistive (CPP-GMR) heads (30-50 nm in size vs. 70 nm today) in products from 2009, with mass adoption in 2011.
Recording density will increase to 200 GB/sq. inch. to 500-1000 GB/sq. inch. opening the door for 4TB HD. This is only by increasing storage capacity, that HD manufacturer's will maintain their market share against the forthcoming invasion of SSD which will initially target markets for handheld and mobile devices.
