Latest Patents
Kimura’s listed patents address tape positioning and reel orientation in magnetic tape drive equipment.
Repositioner for Streaming Magnetic Tape Drive Apparatus
This invention coordinates tape movement and distance measurements to reposition a streaming tape drive. When the system receives a repositioning instruction, its control circuitry stops the reel motor and monitors tape travel. It then reverses the tape and compares forward and reverse travel distances. Once the distances match and a data-block edge is detected, the system signals that repositioning has completed normally. This approach helps prevent adjacent data blocks from being erased and avoids starting data access midway through a block.
Reel Position-Detecting Device
This device determines whether a supply reel has been placed correctly in a magnetic tape drive’s retainer. After detecting the reel, the system rotates the retainer opposite to the tape-supply direction and monitors whether the tape is detected and then ceases to be detected within a set period. The processing unit uses that sequence to distinguish a correctly positioned reel from one installed upside down.
