Patent number: 9904488Abstract: In one embodiment, a product includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. An indicator of a physical position on the magnetic medium that corresponds to an end of the encrypted data is stored on the product. A product according to another embodiment includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. A portion of the unencrypted data is located before the encrypted data on the medium. An indicator of a physical position on the magnetic medium that corresponds to a beginning of the encrypted data is stored on the product.Type: GrantFiled: July 18, 2016Date of Patent: February 27, 2018Assignee: International Business Machines CorporationInventors: Erika M.

Patent number: 9733839Abstract: In one embodiment, an apparatus includes a processor and logic integrated with and/or executable by the processor. The logic is configured to position a magnetic tape volume to a position corresponding to an end of a last data set stored to the magnetic tape volume, and read an existing tape volume access block (TVAB) from the magnetic tape volume in response to a determination that the existing TVAB is stored to the magnetic tape volume. The logic is also configured to write one or more data sets to the magnetic tape volume subsequent to reading the existing TVAB in response to the determination that the existing TVAB is stored to the magnetic tape volume, determine metadata corresponding to the one or more written data sets, and update the existing TVAB with the metadata corresponding to the one or more written data sets to produce an updated TVAB.Type: GrantFiled: September 10, 2015Date of Patent: August 15, 2017Assignee: International Business Machines CorporationInventors: Gavin S.

Patent number: 7111113Abstract: A method to write information to an information storage medium. The method creates one or more objects comprising information and provides a first one of those one or more objects. The method writes a header label to an information storage medium, where the header label comprises an object processing indicator. The method assigns a first sequence number to the first object and writes that first object to the information storage medium beginning at a first blockid and ending at a second blockid. The method writes a trailer label to the information storage medium, where that trailer label comprises an embedded object field count. The method writes an object information block to the information storage medium, where that object information block comprises the first sequence number, the first blockid, and the second blockid.Type: GrantFiled: August 29, 2003Date of Patent: September 19, 2006Assignee: International Business Machines CorporationInventors: Kirby G.
