The friction coefficient is an important parameter in designing magnetic tape transports. We have introduced laser surface texturing to reduce the friction coefficient between guides and magnetic tape. The surface features enhance the formation of an air bearing and hence, reduce the friction coefficient. INTRODUCTION Lateral tape motion (LTM) is defined as the time-dependent motion of the tape...
INTRODUCTION The objective is to evaluate the accuracy of medication dosing and the time to medication administration in the prehospital setting using a novel length-based pediatric emergency resuscitation tape. METHODS This study was a two-period, two-treatment crossover trial using simulated pediatric patients in the prehospital setting. Each participant was presented with two emergent scen...
The purpose of this study was to determine the environmental stability and life expectancies of magnetic media used with certain high density, digital recording tape systems, specifically the IBM 3590 and both Quantum’s Digital Linear Tape (DLT) and Super DLT products. The goal of the study was to compare the tape stabilities and life expectancies of the corresponding tape media and tape storag...
In the mid-1980s, tape storage appeared to be heading toward the graveyard. Storing information on large reels of tape that had to be manually mounted was expensive, inefficient, and prone to human error. In addition, competition from hard disk drives (HDDs) was growing. Data access on HDD was faster because the data was stored in a manner for rapid random access, not linearly as on tape, and H...

Both magnetic wire and acetate-based magnetic tape were used in the audio industry. Welsh and Lukoff [lj describe the early use of metal tape for digital magnetic recording. Acetate-based tape was used for digital recording by Raytheon at a relatively low tape velocity, as reported by Bloch [2]. At IBM it was decided to pursue an acetate-based plastic magnetic tape for computer input,‘ output b...
Fall COMDEX was the center of numerous showings of new tape technologies offering significant increases in tape capacity and performance. Of interest to users of midrange tape technology was the showing of Linear Tape Open (LTO) tape drives. Just as the upstart Linux operating system is nurturing a small but growing base of users, LTOcompliant products promise to secure a significant portion of...
A multi-channel Optical Head has been developed to be incorporated with an Optical Tape Drive that enables greater than 1TB capacity and greater than 25 MB/s data transfer rate on a 0.5 mil thick, 0.5 inch wide optical tape that fits in a 3480 style cartridge. The optical design has been optimized to perform at 532 nm with maximum through put in the write path. With use of a 0.6 NA objective le...
