Magnetic disk storage has shown record growth in 1997, in terms of both units shipments and revenues.
Unit demand is estimated at approximately 125 million drives last year, up from 105 million in 1996.
As for components, head shipments were 6x, and media 3-to-4x, that of rigid disk drives themselves.
Rigid disk drive magnetic head production for 1997 approached 1 billion heads, with disk media slightly under 500 million, according to the 1997/1998 Rigid Disk Drive Head/Media Market and Technology Report (300 pages, $975), published by Peripheral Research (Santa Barbara, CA).
Based on current demand trends, these shipment numbers should double again by the year 2004.
Sub-components further down the food chain, such as suspensions, will be more than 1 billion units in 1997.
Seagate is the worldwide leader in heads (33%), media (23%) and drives.
They have current production at approximately one million heads per day.
