Method, Apparatus And Storage System Having Storage Media With Different Track Pitch Based Upon A Width Of A Write Element Associated Therewith

View page
US Patent:
6778343, Aug 17, 2004
Filed:
Mar 25, 1998
Appl. No.:
09/047610
Inventors:
Lewis L. Nunnelley - San Jose CA
Assignee:
Hitachi Global Storage Technologies Netherlands BV
International Classification:
G11B 2736
US Classification:
360 31, 360 76, 360 7804, 360 48
Abstract:
A method and apparatus is disclosed for providing a track pitch on a recording surface that is associated with the width of the tracks written by the write element of a head therefore reducing the number of heads that are discarded when a fixed relationship between track pitch of storage media in a storage device is desired. The method includes the steps of calculating the width of a write element to be associated with a storage medium and determining the track pitch for the storage medium based upon the calculated width of the write element. The step calculation of the width of the read/write element includes writing a pattern on a storage medium at a predetermined radius using the write element associated with the storage medium to form a written track, moving the head across the written track to read an amplitude sensed from the written track by the head, and ascertaining the width of the write element based upon the sensed amplitude. Ascertaining the width of the write element includes the steps of determining the amplitude of the sensed signal, identifying a one-half amplitude point on a rising edge of the sensed signal and a one-half amplitude point at a falling edge of the sensed signal and computing the distance between the two points. The pattern written on the storage medium may be a constant frequency pattern.

System For Enhancing The Data Storage Security Of Cash-Free Transactions In Vending Machines

View page
US Patent:
7036724, May 2, 2006
Filed:
Apr 30, 2004
Appl. No.:
10/836882
Inventors:
Victoria Elizabeth Lealao - San Jose CA, US
Robert Brooke Martin - San Jose CA, US
Lewis Lee Nunnelley - San Jose CA, US
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
G06F 7/08
US Classification:
235381, 235382
Abstract:
A vending machine has a nonvolatile data storage device for storing transactions with customers. The customers may use a number of cashless options to make purchases from the vending machine, including magnetic credit or debit cards, or universal vending cards. The transactions are stored on the storage device and later retrieved either locally or remotely. The security of the data is enhanced by requiring separate passwords for the data storage device, access to the data storage device, and, optionally for the vending machine controller. In addition, the data is inaccessible should the storage device become separated from the controller.

US Patent:
7313664, Dec 25, 2007
Filed:
Oct 29, 2004
Appl. No.:
10/977314
Inventors:
Lewis Lee Nunnelley - San Jose CA, US
Assignee:
Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam
International Classification:
G06F 12/00
H04K 1/00
US Classification:
711163, 711154, 711164
Abstract:
A data storage device is secured by extracting timing information encoded within a password-related symbol stream received by the storage device and denying access if the timing information is incorrect or the symbol stream is not identical to a valid authentication sequence. In one embodiment, each symbol corresponds to a password, and at least one symbol is transmitted within a specified timing window while at least one other symbol must be transmitted at a random time that varies with each authentication attempt. In certain embodiments, a computing device associated with the data storage device is configured to provide a single password prompt, receive a character sequence corresponding to a plurality of passwords from a user, and communicate an encrypted symbol stream to the storage device with a specified timing pattern imposed thereon.

High Capacity Data Storage System Using Disk Array

View page
US Patent:
54230462, Jun 6, 1995
Filed:
Dec 17, 1992
Appl. No.:
7/993247
Inventors:
Lewis L. Nunnelley - San Jose CA
Larry L. Williams - Los Altos CA
Leighton C. Wood - Morgan Hill CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 126
US Classification:
395750
Abstract:
A data storage and retrieval system is provided which has extremely high capacity. The system includes a large array of small disk files, and three storage managers for controlling the allocation of data to the array, access to data, and the power status of disk files within the array. The allocation manager chooses the disk files upon which incoming data is written based on the current state of the disk files (active or inactive), the available capacity, and the type of protection desired (i. e unprotected, RAID), mirrored, etc. ). The access manager interprets incoming read requests to determine the location of the stored data. The power manager sequences disk files between active and inactive to provide the storage requested by the access and allocation managers. The power manager also maintains the disk array in conformance with thermal and power constraints to avoid excessive power consumption or thermal overload while keeping active the optimal subset of the disk array based on the storage requests pending at any point in time.
