By continuing to drive greater areal
density, we enter new realms of possibility.
interpolation problems often require assumptions to be made regarding the attribute data--with a particular emphasis on the spatial distribution of attributes within areal
units--neural network modeling is a suitable approach to solving such problems.
This is in contrast to the story in magnetic disk where the areal
density growth has slowed significantly with the associated slow down in the improvement in its cost of storage metric.
The companies achieved the areal
density of 36 million bits per square inch with linear densities of over 511,000 bits per inch, track densities of over 70,400 tracks per inch and data rates of 173 million bits per second (21.
Technical advancements in instrument design and geometric theory made these more precise maps possible, and they generally portrayed tangible aspects of the physical world, such as areal
sizes of geographic units, topography, temperatures, and sea depths (Dorling and Fairbairn 1997).
Since the size and number of disk platters are fixed in each defined disk drive format, areal
density is really the only parameter that can be improved to increase storage capacity.
Marvell is pleased to have contributed to Read-Rite's success in achieving record-breaking areal
densities with our 88C4200 PRML read channel product," said Alan Armstrong, vice president of marketing for Marvell's mass storage division.
Hitachi's new areal
density demonstration is not only a testament to the resilience of the 50-year-old technology, but it's also a glimpse into the hard drive crystal ball.
A prominent method in areal
interpolation is dasymetric mapping, defined here generally as the use of an ancillary data set to disaggregate coarse resolution population data to a finer resolution (Eicher and Brewer 2001).
5-inch drives for many applications due to the increasing areal
recording density, unlimited data storage requirements for many applications, as well as constraints on available space in consumer electronics devices.
As the head industry moves rapidly to higher areal
densities, test processes and equipment are becoming more critical for our continued success," said Cyril J.
