AI Technical Summary

Technical Problem

Existing magnetic tape storage systems suffer from limited power supply and low reel motor acceleration, resulting in excessively long head seek times.

Method used

By using a backup power source (such as a supercapacitor) in conjunction with a power distribution module, and controlling the opening and closing of the power supply link and the charging link, the reel motor can be overloaded to increase acceleration and can be quickly charged when no movement is needed.

Benefits of technology

It shortens the magnetic head seeking time and improves the operating efficiency of the magnetic tape storage system.
