Toshiba Claims Bit-Patterned Drive Breakthrough

CWmike writes "Toshiba will detail a breakthrough in data storage later Wednesday that it says paves the way for hard drives with vastly higher capacity than today, reports Martyn WIlliams. The breakthrough has been made in the research of bit-patterned media, a magnetic storage technology that is being developed for future hard disk drives. Bit-patterned media breaks up the recording surface into numerous magnetic bits, each consisting of a few magnetic grains. Under a microscope, the magnetic bits look like thousands of tiny spheres crammed next to each another. Data is stored on these magnetic bits: One magnetic bit can hold one bit of data. Prototypes of the media have been made before but Toshiba says its engineers have, for the first time, succeeded in producing a media sample in which the magnetic bits are organized into a pattern of rows."

Re:Bit = Binary Digit

[sexconker]

It's bad enough we already can't tell whether a "megabyte" is binary or decimal. Now we can't tell whether a "bit" is physical or virtual.

A megabyte always has been and always will be binary-based.

MB is not an SI scalar, nor did it ever pretend to be, nor is it conflicting with the SI scalar M.

The only confusion comes about when you try to insist that MB is infringing on some sacred, arbitrarily-based notion that all major scalars must be factors of 1000.

The "classical" units and scalars are themselves ambiguous. What does M mean? Meter? Mass? Minute? Mega? Milli? What does G mean? Gram? Giga? The gravitational constant? Is K kilo? Is it the spring constant? Is it Kelvin?

You can impose all the capitalization and styling rules you want, but the bottom line is that people cannot distinguish the 17 ways you write the letter "u", nor will they replicate them easily or reliably.
People read technical descriptions in context.

When you see MB, you KNOW you're talking about megabytes, and you KNOW bytes are binary. If you fail at this, you're either a marketer for storage devices (liar), or you should not be working with computer-related things.

Re:I read TFA

[noidentity]

I read TFA. They claim that this will increase the density 5x.

Actually, the article actually only claims about a 4x increase (actually only 3.62):

Toshiba's sample media is still in the prototype stage, but is built at a density equivalent to 2.5 terabits per square inch. Contrast that with Toshiba's current highest capacity drive today, which is based on existing technology and has a density of 541 gigabits per square inch or about one fifth that of the new technology.
