Concurrent logging of data layers within a tape storage device
Concurrent standard/high resolution logging of critical performance metrics and functional data for various functional areas including servo system, dataflow, channel, read/write, speed matching, and error recovery is achieved by segregating one or more rows of the tape map array for the purpose of logging only high resolution data. As performance data is logged to the standard resolution tape map by wrap and regional offset down tape, the reserved high resolution row logs data sequentially in the order it was processed on magnetic tape and not by its position on magnetic tape. The high-resolution performance data is concurrently logged with normal-resolution performance data as a supporting view with more detailed tape processing data should the normal-resolution performance data have inconclusive or insufficient content. High-resolution storage is structured for shorter regional logging or per-dataset logging of critical performance metrics and functional data, referred to herein as performance data. |

Continuous-flow dryer comprising a first and a second section
A continuous-flow dryer for drying a material by hot air is provided with a first and a second section, through which the material is passed successively in a transport direction. It includes a fresh air supply device, an exhaust air recirculation device for removing exhaust air and recirculating it as supply air, and a heat exchanger, through which fresh air and exhaust air are led, for transferring waste heat of the exhaust air into the fresh air. With the exhaust air recirculation device a first part of the exhaust air is removed from the first section and recirculated as supply air directly into the first section. Furthermore, a second part of the exhaust air is removed from the first section, led through the heat exchanger, and recirculated as supply air into the first section. The fresh air supply device supplies fresh air as supply air into the second section. |
