Frequency domain subspace identification of a tape servo system
As capacity demands for magnetic tape storage systems grow, servo actuator design for tracking data on high density tape media presents new modeling and control design challenges. In this paper a frequency weighted subspace identification algorithm is presented for control relevant model estimation of a tape servo actuator. Common to other subspace identification methods, the proposed algorithm...
متن کاملUsing Track-Following Servo Technology on LTO Tape Drives
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...
متن کاملForensic Examination of CCTV Digital VTR Surveillance Recording Equipment
Approximately two years ago I authored a paper entitled, “The Forensic Examination of Video Recordings” which discussed some of the more conventional forensic techniques for examining questioned analog videotapes regarding their originality and for possible evidence of tape alteration. This paper specifically addressed the various mechanical and electrical signal anomalies that occur when editi...
متن کاملBer Performance Comparisons in Digital Tape Recording
Bit-error-rate (BER) performances of various DC free coding and detection methods have been compared in digital tape recording environments. Performance sensitivities to additive noise, head-tape space variations and o track interference have been investigated at two representative linear densities. The results indicate that the performance ranking of di erent techniques depends strongly on the...
متن کاملCharacterization of lateral tape motion and disturbances in the servo position error signal of a linear tape drive
Lateral tape displacement in a tape drive is believed to be one of the critical limiting factors in achieving high track density in tape storage media. For improving track density, servo control systems can be designed on the basis of information from a position error signal to improve the track following capabilities in a tape drive. In this paper, we consider the characterization of lateral t...
