This combined with a 48nm wide (TMR) hard disk drive read head enables a track density of 246,200 tracks per inch, a 13-fold increase over a state of the art TS1155 drive.
Functionally, interposers are similar to double-sided PCBs but with top-side track density up to 500 traces/mm--about 100x the density of a fine-trace PCB--and too tight to probe, although the bottom-side microbumps can be probed.
The variables we used in the candidate models were the following: female age (two categories: first breeder & older), body mass of the hen (in g), hatching date (1 = earliest nest of the study), microfilaria (n), trypanosoma (presence/absence), hematocrites (in % red blood cells), clutch size (n), mean chick mass (in g), bilberry cover (in %), heather cover (in %), grassy vegetation cover (in %), tree density (number/ha), shrub density (number/ha), canopy coverage (in %), visibility (in metres), drainage (two categories: drained/not drained), rainfall (in mm), temperature (in[degrees]C) and predator track density (tracks/24 hours/10 km).
The Carpathian method is based on the relationship between absolute population density (N/1,000 ha), as an independent variable, and a snow track density index (T/km/day) as a dependent variable.
The other avenue that tape has room to grow is in track density.
Speed and flexibility are key features and although the machining time is dependent on track density, simple boards take just minutes while even complex multilayer boards only take a few hours.
It will have a higher track density than LTO and, according to the senior marketing manager for Quantum's advanced products group, Geoff Hogan, has already undergone a change in specifications since the Milipitas, California-based company announced the project a year ago.
during our experimental period), breeding raptors may contribute to summer crashes of voles, although outside the breeding season they are free to search for areas of high vole density and may rapidly track density fluctuations of vole populations (Galushin 1974, Korpimaki 1985, 1994).
These performance limits in turn curb increases in track density.
Helical-scan decouples the tape track density from the number of heads in the drive by mounting the read/write (R/W) heads on a drum called a scanner that rotates at high speed.
These correspond to a track density of 1,245 tracks per inch (TPI), far denser than the 48 to 135 TPI on conventional magnetic floppies, though nothing like the 15,000 TPI on an optical disc.
