Patent number: 8238217Abstract: The present techniques provide methods and systems for enhancing a data signal in reading optical discs, such as holographic data discs. The techniques involve adjusting the position of a detector, or multi-pixel detector, such that the reflection corresponding to a micro-hologram or micro-reflector is enhanced. For example, the detector position may be adjusted to a position where the surface reflection and the micro-hologram reflection constructively interfere, resulting in an amplified micro-hologram reflection signal. Other parameters such as disc reflectivity and detector pinhole size may be adjusted to increase signal enhancement. Furthermore, the detector position may be adjusted to a position where the phases of the surface reflection and the micro-hologram reflection result in a weaker cross term.Type: GrantFiled: December 16, 2008Date of Patent: August 7, 2012Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Xiaolei Shi

Patent number: 8233368Abstract: The present techniques provide methods and systems for more reliable reading of optical data disks. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The pattern may include light scattered from a single bit that may be under a center detector, as well as light scattered from proximate bits. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the presence or absence of a bit or bits of data. The mathematical combination may also use data that is known about the status of adjacent data bits (such as previously read bits, or bit patterns which are allowed or not allowed by specific data encoding schemes) to improve the accuracy of the bit prediction.Type: GrantFiled: December 18, 2008Date of Patent: July 31, 2012Assignee: General Electric CopanyInventors: John Anderson Fergus Ross, Kenneth Brakeley Welles, John Erik Hershey, Xiaolei Shi, Victor Petrovich Ostroverkhov

Publication number: 20120170437Abstract: Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.Type: ApplicationFiled: December 29, 2010Publication date: July 5, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: John Erik Hershey, Kenneth Brakeley Welles, John Anderson Fergus Ross, Xiaolei Shi, Zhiyuan Ren, Victor Petrovich Ostroverkhov

Patent number: 8125862Abstract: The present techniques provide methods and systems for alignment of a read head with data tracks on an optical data disk. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the alignment of the read head with a target data track. If the read head drifts to one side or the other, detectors to the side of a center detector may start to pick up energy from the adjacent tracks. If this energy is continuously summed for the detectors on each side, the read head may be centered by balancing the sums from the detectors on each side.Type: GrantFiled: December 18, 2008Date of Patent: February 28, 2012Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Kenneth Brakeley Welles, John Erik Hershey, Xiaolei Shi, Victor Petrovich Ostroverkhov

Patent number: 8089846Abstract: The present techniques provide systems and methods for modulation coding of data on optical disks, such as holographic data disks, and techniques for reading that data back from the disks. The techniques involve parsing a bit stream into a sequence of individual bit-patterns, and then using the individual bit patterns to select a symbol, or matrix, from a lookup table of previously selected matrices. The symbols are selected according to predetermined criteria that may help make the disk more resistant to interferences and errors, such as surface scratches, and the like. For example, criteria that may be used to select the symbols are the number of reflective and non-reflective regions within each matrix, and the number of sequential reflective regions, among others. The symbols may be written to the disk in a two-dimensional fashion, e.g., across adjacent tracks, or in a three-dimensional fashion, e.g., across adjacent data layers.Type: GrantFiled: December 16, 2008Date of Patent: January 3, 2012Assignee: General Electric CompanyInventors: John Erik Hershey, Nick Andrew Van Stralen, Harold Woodruff Tomlinson, Jr., John Anderson Fergus Ross, Zhiyuan Ren, Zexin Pan, Victor Petrovich Ostroverkhov, Xiaolei Shi
