Patent number: 8725943Abstract: A method and system for secure data storage and retrieval is provided. A sequence of data units is divided into multiple subsets of data units corresponding to multiple data channels. The multiple data channels are assigned to multiple data writers based on a key code. Then, each subset of data units is transferred to a writer via an assigned channel for writing to storage media. Thereafter, to securely retrieve the stored data, each subset of data units is read from the storage media using a data reader. The original sequence of data units can only be reassembled using the key code for properly reassembling the subsets of data units into their original sequence.Type: GrantFiled: January 16, 2013Date of Patent: May 13, 2014Assignee: International Business Machines CorporationInventors: Peter VanderSalm Koeppe, Jason Liang

Patent number: 8233246Abstract: A magnetic head comprises identical, opposing modules each comprising an array of paired data transducers, the transducers including data readers, data writers, or combinations thereof. For each array, the transducers in each subset may have about the same center to center spacing. A first subset of the transducers is operable for reading or writing data in a first tape format. A second subset of the transducers is operable for reading or writing data in a second tape format, with at least some of the transducers being present in both subsets. Also, each module includes a lone writer at one end of one of the subsets, a lone reader at an opposite end of the one of the subsets, and servo readers positioned outside the array.Type: GrantFiled: March 12, 2008Date of Patent: July 31, 2012Assignee: International Business Machines CorporationInventor: Peter VanderSalm Koeppe
