The hard drive-maker said it has created the world's smallest disk drive heads -- about 2,000 times smaller than the width of a human hair.
SAN JOSE, Calif. (AP) -- Multimedia stockpilers need not worry about laptops, digital video recorders or portable music players hitting a storage capacity ceiling any time soon.
Hitachi Ltd. (Charts) says its researchers have successfully shrunken a key component in hard drives to a nanoscale that will pave the way for quadrupling today's storage limits to 4 terabytes for desktop computers and 1 terabyte on laptops in 2011.
A terabyte can hold the text of roughly 1 million books, 250 hours of high-definition video, or a quarter million songs.
"It means the industry is making good progress to advance the capacity of disk drives and move to smaller form factors," said John Rydning, an analyst at market research firm IDC.
