Paper Abstract

Synthetic aperture radar generates large images. The storage and retrieval of these images from an archive supports the operational utilization of newly generated images. In addition to archiving the new images for reference, supporting images are stored in the archive. An optical disk jukebox with a capacity of 500 gigabytes to 1 terabyte provides an essential element of the storage of the archived images. The optical jukebox supports the rapid retrieval of images that are as large as 20 megabytes with no compression. With compression, the images that can be effectively stored on the optical jukebox can be as large as 200 megabytes. Images are typically pre-fetched a few minutes before they are needed. Ad-hoc images may be fetched in less than a minute for the smaller images. For the larger images the time to fetch the image is established by the time to read the image from the optical disk. This paper compares the storage on the optical jukebox with competing storage on helical scan tape.
