Toshiba has revolutionized the way bits of data are arranged on hard drive platters. Traditionally, the bits are placed end to end. This layout has an inherit problem; you can only put so many bits together before they start randomly switching their orientation thereby corrupting data. Toshiba's new technology has taken 20 years to develop and is a big step in the right direction for increasing hard drive capacity without increasing size and power consumption. The new layout stands the bits up on their ends which allows more bits of information to fit in the same area. Think of the current technology as pens lying end to end. Toshiba has figured out how to stand the pens up vertically. Instead of your pens lying out over a foot long, you can now get the same amount of pens in a much smaller space. This technology can bring high capacity HDDs to cellphones, PDAs, & MP3 players. The possibilities are limitless! Look for Toshiba's "Gigabit" player as it will be released soon with a 1.8" single-platter 40gig drive!
