Bounding Defective Regions Of A Tape Storage Medium
View pageUS Patent:
7269687, Sep 11, 2007
Filed:
Aug 20, 2004
Appl. No.:
10/923443
Inventors:
Dwayne A. Edling - Longmont CO, US
Charles Klomp - Boulder CO, US
Charles Klomp - Boulder CO, US
Assignee:
Quantum Corporation - San Jose CA
International Classification:
G06F 12/00
G11C 29/00
G11C 29/00
US Classification:
711111, 711156, 714771
Abstract:
Systems and methods for storing data on a tape medium and coping with defective regions on the tape medium are provided. The method includes: writing a plurality of envelopes of data onto the tape medium, each envelope of data comprising a plurality of blocks of data; detecting a defective region of the tape medium; writing a boundary start field after the defective region, the boundary start field indicating that the defective region has been passed; and writing a boundary end field before the defective region of the tape medium, the boundary end field indicating that the defective region follows the boundary end field.

International Classification:
G06F 12/14
US Classification:
713193000
Abstract:
Data stored on a removable storage medium such as a tape cartridge can be protected from unauthorized access by storing a password hash value in a protected manner on the storage medium, where the password hash value is generated from a password by a one-way hash function such as SHA-256, so that the password cannot easily be determined from the hash value. A media drive is then equipped with logic for blocking access to the data unless the password is provided. The password is protected from unauthorized access because the password hash value, not the password itself, is stored on the storage medium.
Magnetic Tape Drive With End-Of-Track Block Directory
View pageUS Patent:
55462464, Aug 13, 1996
Filed:
Jan 13, 1994
Appl. No.:
8/181317
Inventors:
Charles B. Klomp - Saline MI
Mark R. Ayers - Whitmore lake MI
Daniel J. Canterbury - Howell MI
Mark R. Ayers - Whitmore lake MI
Daniel J. Canterbury - Howell MI
Assignee:
Exabyte Corporation - Boulder CO
International Classification:
G11B 1518
US Classification:
360 722
Abstract:
A magnetic tape drive system (20) records a directory block (CL) at a predetermined position on tape (22), and preferably at the beginning of tape. The directory includes, for each recorded track on tape (22), a data block number of the data block recorded at an end of the track. Preferably a plurality of copies of directory block (CL) are recorded, preferably in reverse direction. Upon receipt of a command to locate a target data block recorded on tape (22), a processor (102) directs a transport controller (82) to position a read element (30R) at the predetermined position on tape (22) for reading the directory. The read element reads the directory from tape (22). The processor (102) compares the target block number with the data block numbers stored in the directory and, in response to the comparison, causes an element positioner (74) via the transport controller (82) to position the read element with respect to the width of the tape (22) so as to read the track upon which the data block having the target data block number is recorded. The track upon which the target data is located is then sequentially searched for the target data block.
