In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase.

A method and apparatus for recording on an optical recording medium, including the recording of management information, are described as a standard for the write-once Blu-ray disc. The management information is recorded in a management area of the disc, such as a temporary defect management area (TDMA), and includes record status information and update information. The record status information is a space bitmap (SBM) indicating whether a recording operation has been performed for a predetermined area of the disc, and the update information is SBM update information indicating whether the record status information is to be continuously managed. The SBM update information controls the state of an SBM-on/off function for each of a plurality of recording areas and may be in the form of either start position information and length information corresponding to the respective areas or an SBM update flag. The SBM update information is recorded in the TDMA and is stored in a memory of an optical disc recording/reproducing device for use during recording and reproducing operations. At the time of recording in the predetermined area, an SBM-on state enables a logical overwriting operation to be performed as necessary.

This method of loan settlement is accomplished by providing automated document production through the internet for all documents relating to a loan settlement, particularly a par loan trading settlement. Once the information is entered by the client and supplemented by the automated system, the system enables the buyer and the seller, on their business or home computers, to access such documents and information, immediately and in a secure and efficient manner. The system itself is accomplished easily by the use of state-of-the art hardware, software and internet links. The system expedites closing, and is used, as well, for settlement of original loans, and/or loans for distressed entities.

Attributes of a hard disk drive are stepped between different power consumption levels to optimize the trade-off between minimizing power consumption and maximizing performance depending on whether AC or battery power is used. One attribute is the clock speed which can be changed for a number of disk drive components including the processor, the external interface bus and the memory interface bus. The system power supply voltage can further be changed in a number of components integrated together on an application specific integrated circuit (ASIC). Further, spindle motor rotation speed can be changed, or the spindle motor spun-down. Further, actuator movement by the VCM can be controlled to provide faster movement during track seek operations when high performance is desired. Additionally, write-back caching parameters are adjusted based on the source of power for the hard drive, be it battery, AC power, or a combination.

The invention discloses the technical field of network data transmission safety centering on contents and discloses a broadcast encryption transmission method in a network based on identification and centering on the contents. A content provider requests user identification through a broadcast interest package, a user can send identification information ID representing a public key to the content provider, the content provider uses a broadcast encryption algorithm based on the identification to encrypt plaintexts and then broadcasts the user, only a target user in user collection can decode the obtained plaintext contents, and the user collection can be composed of any user. When the user collection only has one user, a protocol is an end-to-end encryption transmission protocol. When the user collection has multiple users, the protocol is a broadcast encryption transmission protocol, and times of broadcast content encryption transmission are reduced. The method can enable the user identification to be added into the user collection to achieve content access controlling, and achieves data source authentication, data integrality and confidentiality protection based on an autograph of the identification and a broadcast encryption scheme.
