| 369590260 | Binary signal processing of sectioned information | 8 |
| 20080225666 | RECORDING MEDIUM PLAYBACK DEVICE AND RECORDING MEDIUM PLAYBACK METHOD - There is provided a recording medium playback device that includes a first binarization portion that binarizes, by a PRML method, a signal that is read from a recording medium, a second binarization portion that binarizes the signal based on a magnitude relationship to a specified threshold value, a first frame synchronization signal detection portion that detects a synchronization pattern in a first binarized data string that is produced by the first binarization portion, and a second frame synchronization signal detection portion that detects a synchronization pattern in a second binarized data string that is produced by the second binarization portion. If the synchronization pattern is not detected by the first frame synchronization signal detection portion, a signal that is derived from the synchronization pattern that is detected by the second frame synchronization signal detection portion is used as the frame synchronization signal. | 09-18-2008 |
| 20080239917 | AUDIO DATA OUTPUT APPARATUS AND AUDIO DATA OUTPUT METHOD - According to one embodiment, a preset amount of padding data is added while a block number corresponding to a detecting period of sync information which becomes shorter is used as a packing unit when the detecting period of the sync information becomes shorter than an original period, and a block number corresponding to a detecting period of the sync information which becomes longer is divided while an original number of blocks contained in one packing unit is set as an upper limit and a preset amount of padding data is added with each divided block number used as a packing unit when the detecting period of the sync information becomes longer than the original period. | 10-02-2008 |
| 20090067309 | OPTICAL DISC MANUFACTURING METHOD AND DEVICE, OPTICAL DISC, AND OPTICAL DISC REPRODUCTION METHOD - According to the present invention, there is provided a method of recording a unique ID to a read-only optical disc based on the 17PP modulation. The read-only optical disc ( | 03-12-2009 |
| 20090073841 | METHOD AND APPARATUS FOR RECORDING DATA ONTO AN OPTICAL DISC - A method of recording information onto an optical disc of the rewritable type, the disc comprising a spiral track, at least part of the track being arranged as a recording area for recording the information, the recording area being further divided into sequential, independently addressable units of pre-determined size, pre-determined numbers of addressable units being grouped in recording unit blocks comprising: deciding for at least an recording unit block that it will be recorded; determining direct overwrite information for said recording unit block, the direct overwrite information comprising information with respect to the number of times the recording unit block was previously recorded; encoding and recording the information into the recording unit block and updating the direct overwrite information for the recording unit block, the direct overwrite information being recorded within the recording unit block. The method also comprise that before recording, reading the said direct overwrite information and adapting Write Strategy and Write Powers accordingly. | 03-19-2009 |
| 20090141606 | METHOD AND SYSTEM FOR MANAGING DATA FROM HOST TO OPTICAL DISC - A method for managing data from a host to an optical disc includes: storing data into a write data queue (WDQ) when the data of sequential write commands from the host are write-address-discontinuous; and transferring specific data from the WDQ to a write buffer when an available memory space in the WDQ is lower than a first threshold value or an available memory space in the write buffer exceeds a second threshold value. | 06-04-2009 |
| 20090161514 | INFORMATION RECORDING APPARATUS, INFORMATION READING APPARATUS AND COMPUTER READABLE MEDIUM - An information recording apparatus includes an information obtaining unit, a sign arrangement generating unit, a sign arrangement recording unit. The information obtaining unit obtains information to be recorded on a recording medium. The sign arrangement generating unit, based on information to be obtained by the information obtaining unit, generates an arrangement having three or more kinds of signs for expressing the obtained information. The sign arrangement recording unit, while shifting recording positions of a recording area included in the recording medium, records physical features sequentially into the respective recording positions of the recording area included in the recording medium. And each physical feature corresponds to one kind of the signs. | 06-25-2009 |
| 20110182162 | High-Speed Multi-Layer Optical Disc Recording - An apparatus includes a recorder having at least two optical pickup heads for simultaneously recording at least two bit streams on respective layers of recordable media in one of an opposite track path and a parallel track path. | 07-28-2011 |
| 20150043321 | CHANNEL BITWORD PROCESSOR, PRML DECODER, AND OPTICAL INFORMATION RECORDING/REPRODUCING DEVICE - It is an objective of the present invention to provide a technique, when using fixed-length run-length limit codes based on enumeration, that generates fixed-length channel bit words satisfying maximum run-length limitation using a simple configuration. A channel bit word processor according to the present invention includes an avoidance list that describes a difference between a user bit word satisfying a maximum run-length limitation of run-length limit code and a user bit word not satisfying the maximum run-length limitation. The channel bit word processor, if a user bit word does not satisfy the maximum run-length limitation, generates a channel bit word using a user bit word after the difference is added. | 02-12-2015 |
