Publication number: 20120212846Abstract: A method of calibrating a servo reader and a read/write head for a data storage tape machine that reads and writes data to a data storage tape. The data storage tape has a servo pattern that is recorded on the tape in a known location. The servo pattern is used to provide precise position information for the data storage tape. According to the method, data is recorded on the data storage tape and the location of the data storage track is read. The location of the data storage tape is compared to the known location of the servo pattern to establish a reader offset value. The data storage tape machine is updated based upon the reader offset value to adjust the position of the read/write head.Type: ApplicationFiled: February 23, 2011Publication date: August 23, 2012Applicant: ORACLE INTERNATIONAL CORPORATIONInventors: Steven Michael Kientz, Keith Gary Boyer, Matthew K. Tucker

Patent number: 7130140Abstract: Servo tracks for magnetic tape storage are written using two opposite polarities, rather than the one polarity normally used in servo tracks. Timing continues to be performed using only pattern members of like polarity, due to physical restraints, but the use of two polarities allows additional information to be encoded in the pattern more efficiently.Type: GrantFiled: May 6, 2002Date of Patent: October 31, 2006Assignee: Storage Technology CorporationInventors: Keith Gary Boyer, James C. Cates, James William Wolf

Patent number: 7130139Abstract: A drive and method of identifying write velocity during reading are provided. When a track is being read, the data signal is processed prior to determining the data stream to identify the velocity with which the track data were written. The read channel is adjusted based on the identified velocity to compensate for write channel transfer function variation.Type: GrantFiled: July 7, 2005Date of Patent: October 31, 2006Assignee: Storage Technology CorporationInventors: Keith Gary Boyer, Richard Allen Gill

Patent number: 7055081Abstract: In a magnetic recording device, a system and method for correcting errors in decoding a read data input signal. The system and method include multiple decoding channels, each channel processing the read data input signal and generating an output signal, where the output signal includes a data signal when no error is detected, and an error detection code when an error is detected. The system and method also include multiple error correction code (ECC) decoders, each decoder associated with and receiving the output signal of one of the channels and generating a corrected data signal when the received output signal is an error detection code and the error is correctable. The system and method further include a controller for selecting from the decoders one of the corrected data signals.Type: GrantFiled: March 2, 2001Date of Patent: May 30, 2006Assignee: Storage Technology CorporationInventors: Keith Gary Boyer, Kevin M.

Patent number: 6981198Abstract: A method and system are provided for dynamically shortening a number of error correction codewords to correspond to an amount of user data to be recorded on a recording medium. The system and method determine in advance that the number of bytes of user data will only fill a portion of a codeword matrix, and automatically shortens the size of ECC word segments to match the actual user data fill. This allows an ECC interleave to be completed with only a partial fill of the matrix, thereby reducing the required number of recording passes and associated processing time.Type: GrantFiled: April 26, 2001Date of Patent: December 27, 2005Assignee: Storage Technology CorporationInventors: Keith Gary Boyer, Richard Allen Gill

Patent number: 6956709Abstract: A tape drive and method of identifying write velocity during reading are provided. When a track is being read, a lead-in code of the data signal is processed prior to determining the data stream. The lead-in code identifies the velocity with which the track data were written. The equalization/detection channel is adjusted based on the identified velocity to compensate for write channel transfer function variation. The lead-in code is coded in a way that is reasonably immune to write channel transfer function variation such that the lead-in code is comprehended prior to adjusting the equalization/detection channel.Type: GrantFiled: June 7, 2004Date of Patent: October 18, 2005Assignee: Storage Technology CorporationInventors: Keith Gary Boyer, Richard Allen Gill

Patent number: 6947241Abstract: An asynchronous method for locating individual blocks of data in a tape drive, without having to read the blocks of data is provided. The invention comprises placing an ID mark adjacent to the data blocks and inter-block gaps on the tape. The ID mark contains a small amount of information about the next respective data block on the tape. The ID mark is encoded such that the same detection mechanism that detects the inter-block gap can also retrieve the ID mark information, without having to process the entire block of data associated with a particular ID mark. The ID mark is symmetrical such that it can be detected and decoded in the forward and backward direction, allowing the tape drive to find a desired block of data by searching either forward or backward, even when the magnetic tape uses a unidirectional data format.Type: GrantFiled: August 7, 2002Date of Patent: September 20, 2005Assignee: Storage Technology CorporationInventors: Richard Allen Gill, Roger D. Hayes, Keith Gary Boyer

Patent number: 6937412Abstract: A method, apparatus, and computer instructions for writing data to a magnetic media. A first frequency is written on a first track on the magnetic media on a first track width. A second frequency is written on the first track in which a combination of the first frequency and the second frequency encodes a bit of data on the first track. An erase pattern is created on a second track on the magnetic media, the second track being adjacent to the first track in which the bit of data on the first track is readable by a tape drive system having a second track width wider than the track width of the first track.Type: GrantFiled: July 26, 2002Date of Patent: August 30, 2005Assignee: Storage Technology CorporationInventors: Richard Allen Gill, Roger D.

Patent number: 6898036Abstract: A system and method for recovering from write errors during writing of a moving storage medium suspend write current while allowing the storage medium to continue moving. The system and method continue to format data for writing while the write current is suspended and resequence the data for subsequent storage. Information is recorded to distinguish previously written data from current data with error correction pointers adjusted accordingly. Write errors may be detected in a track following streaming tape system based on data errors from a read back check or based on positioning errors of a read/write head servo system, for example. By allowing the storage medium to continue moving through the error event, the system and method improve speed, capacity utilization, and throughput of the storage and retrieval process.Type: GrantFiled: December 31, 2001Date of Patent: May 24, 2005Assignee: Storage Technology CorporationInventors: Richard Allen Gill, Keith Gary Boyer, Steven Gregory Trabert
