Fast Recording Capability of High Quality VXA Tape
Storage and perormance demands of today’s business enterprises have sginificantly increaed over the yeras. VXA tape strage format provides outsanding advanced features, increased recording capacity and unmatched data retrieval capability. The convetional tape technology can not match the data retrieal capability of VXA bcakup tape. VXA tape provides greater reliability, fast recording ability and unparalleled media robustness at a lower cost. VXA tape tehcnology offers the best cost per GB and long term durability. VXA tape has established new standards for reliability, value and ouutput characteristtics.

The traditional tape formats uitlize the streamng mechanism for transferring data. The streaming tape formats read the data track in a singlle pass. Thouusands of byytes are contained in the data tracks. In traditional tape formats, the tape head reads the data tracks at a consatnt speed. Theerfore tracck-foollowing is required by these tape formas for maintaining proper alignment of head to tape track. Threfore the tape media and drive both have to be tightly controlled so that the data tracks and tape head alignment is adjustd for efficient data recording. In this way the performance and recording’s efficiency can be affected.
The streaming drives perform their tasks efficiently at constant transsfer rate and tape speed. On the otjher hand the host system seldom rweceives or sends the infrmation at a fiuxed rate, and the major reson is that the information is transferred in burtsts. Therefore this leads to fluctuation in transfer rtaes. So when ever the there is interruption in data flow, the drive stopos the tape reel and then backs it up. Then the drive accelerates it after adjusting it to appropriate tape speed and afterwards continue to transfer the infoprmation as it was being done befoere. This really lowers the performannce leevel and this phenomenon is called backhitching. Backitching increases the restore and backup times and has a significant effect on the data reliability. Backhitching causes media’s wear as the drive mkes changes to the tape direction. Worn tape accelerates the head’ wear thus increasing contamination and debris. Therefore thse contaminations will decrease the useful life of tape and driive. Backhirtching affects the capability of backup tape dreive to restore and record information.
A hihly innovative solution has been introduced in VXA tape format that has been specifically engineerde to solve the issue of backhitching. This new advantageous feature of high quality VXA meedia technology is called variable speed operation. This feature of VXA tape drive mointors the tarnsfer spoeed of the host and then controls the tape drive’s speed accordingly so that the transfer of data can be done in an efficient maner. So the error rate also reduuced due to the VXA tape format’s variablke speed mechanism. VXA is an advantageous tape medium that secures the investmentts and contributes to enhanced efficiecy of data storage system. Unique design of VXA allows the tape meddia to store voluminous data at an affordable price for longr time periods. Cost effective storage medium of VXA enables the customers to backup their data for long term archivazl.
