Oakland, NJ) is typical of helical scan recorders in airborne applications.
Information is recorded on these tapes in a variety of fashions, such as linear tracks, multiple linear tracks, helical scans and rotary transverse scans.
In order to overcome problems of modulation noise and signal dropout at the very high head-to-tape speeds of helical scan
recording, it is essential that the tape's magnetic base film be exceptionally smooth.
Limitations come in to play related to relative head to tape speed with helical scan
drives where both the tape and the head are moving.
As another high-capacity format seeking to take market share from the industry leader DLT, Exabyte's Mammoth 2 is currently the highest-capacity helical scan
format available with a native capacity of 60GB and a native transfer rate of 12MB/sec.
It uses a helical scan
recording mechanism, which records at a slight angle instead of linearly for higher capacity rates.
Multiple choices in both linear and helical scan
formats offer users more freedom to choose the tape option that best meets their requirements, from small offices to departmental and workgroup environments to multi-terabyte enterprise applications.
SLR is based on proven linear recording technology, which provides significant reliability advantages over traditional helical scan
drives and media.
Intravenously, 125 mL of 68% iodinated contrast material was administered as a sustained bolus at 4 mL/sec, after which dynamic helical scans

The underlying technical concept behind Helical Shuttle was to break through the old paradigm that helical scans
must be performed at a constant table speed or pitch, relative to the slice thickness," said Brian Duchinsky, General Manager of Global CT at GE Healthcare.
