Abstract:  Over the past 20 years tape’s role has evolved from a backup usage model to an archiving one, and as a result most customers now use new tapes for one-time archiving operations. The impact of newly manufactured media on tape head life and drive performance is a topic that has been discussed for decades, and the causes of head damage related to the use of “green” media are well understood. Many articles have been published describing the causes and proposing solutions, yet customers continue to report problems when using new media.  In fact, the archive usage model means that drive damage caused by “green” LTO media is on the increase.  A simple examination of the surface of newly manufactured media clearly shows the root cause: new media is characterized by excessive surface asperities and contamination. The asperities result in head pole tip recession, causing permanent tape-to-head separation and subsequent signal degradation, ultimately leading to drive failures. Additionally, contamination from the manufacturing process can be observed on the surface of newly manufactured media. Tape surface contaminants cause head clogging and increased drive error rates. Despite the media manufacturers’ best efforts to reduce tape asperities and contamination, problems with freshly manufactured media persist. This paper demonstrates that the patent-pending NanoPure Media certification process significantly reduces error rates on new LTO media, addressing one of the main challenges of the archive usage model. Furthermore, since new cartridges are not calibrated at the factory, when a tape system fails due to excessive data errors, there is currently no reliable way to determine if the cause of the error is the drive or the cartridge, as it is not possible to account for cartridge-to-cartridge data error differences. Presently, the drive diagnosis options are lengthy, complex and costly.   For example, when a tape drive fails within a media library, it is not possible to determine with certainty if the cause of the failure is marginal head performance, or the tape media itself, as both can produce data errors.   In the case of a tape library, where multiple drives record data on the same cartridge, it is then virtually impossible to determine the marginal drive or cartridge that caused the error. NanoPure Media is calibrated in such a way that the root cause of the errors can be determined with certainty. 

摘要：在過去的 20 年裡，磁帶的角色已經從備份使用模型演變為歸檔模型，因此大多數客戶現在使用新磁帶進行一次性歸檔操作。 新製造的介質對磁帶磁頭壽命和驅動器性能的影響是一個已經討論了數十年的話題，與使用“綠色”介質相關的磁頭損壞原因也廣為人知。 已經發表了許多描述原因並提出解決方案的文章，但客戶在使用新媒體時仍不斷報告問題。 事實上，歸檔使用模型意味著由“綠色”LTO 介質造成的驅動器損壞正在增加。 對新製造的介質表面進行簡單檢查即可清楚地發現根本原因：新介質的特點是表面粗糙和污染過多。 粗糙的結果在磁頭極尖後退中，導致磁帶與磁頭的永久分離和隨後的信號衰減，最終導致驅動器故障。 此外，可以在新製造的介質表面觀察到製造過程中的污染。 磁帶錶面污染物會導致磁頭堵塞並增加驅動器錯誤率。 儘管介質製造商盡最大努力減少磁帶粗糙度和污染，但新製造的介質問題仍然存在。 本文證明了正在申請專利的 NanoPure Media 認證過程顯著降低了新 LTO 介質的錯誤率，解決了存檔使用模型的主要挑戰之一。 此外，由於新盒帶在出廠時未校準，當磁帶系統因過多的數據錯誤而出現故障時，目前沒有可靠的方法來確定錯誤的原因是驅動器還是盒帶，因為無法確定 考慮墨盒到墨盒的數據錯誤差異。 目前，驅動器診斷選項冗長、複雜且成本高昂。 例如，當媒體庫中的磁帶驅動器發生故障時，無法確定故障原因是磁頭性能不佳還是磁帶介質本身，因為兩者都會產生數據錯誤。 在磁帶庫的情況下，多個驅動器將數據記錄在同一個盒式磁帶上，因此幾乎不可能確定導致錯誤的邊緣驅動器或盒式磁帶。 NanoPure 介質經過校準，可以確定錯誤的根本原因。
