摘要:
Systems and methods that substantially or fully remove a commanding server from a data path (e.g., as part of a data migration, disaster recovery, and/or the like) to improve data movement performance and make additional bandwidth available for other system processes and the like. Broadly, a network interface card (e.g., host bus adapter (HBA)) of a tape drive may be configured in both a target mode to allow the tape drive to be a recipient of control commands from a server to request and/or otherwise obtain data from one or more source tape drives, and in an initiator mode to allow the tape drive to send commands to the one or more tape drives specified in the commands received from the server to request/read data from and/or write data to such one or more tape drives.

The present invention relates to a system for verifying data recorded on an information recording medium. The system includes a data reproduction unit for reproducing data recorded on an information recording medium, a reproduction-verification-data generation unit for executing a calculation based on the data reproduced by the data reproduction unit to generate reproduction verification data, and a data comparison unit for comparing the reproduction verification data with recording verification data, which is obtained by executing a calculation based on data to be recorded on the information recording medium.

A storage controller of the present invention makes use of the differences in power rates by time zone and geographic region to control the data storage destination between storage devices of different power consumption. The storage controllers of respective sites each comprise a hard disk and flash memory device, which consume different amounts of power. A schedule manager manages a schedule for controlling the data storage destination utilized by the host. At night, when the power rate is low, data is copied from a hard disk to a flash memory device. In the daytime, when the power rate is high, an access from the host is processed using the data inside the flash memory device. Copying data between remote sites makes it possible to reduce the power costs of the storage system as a whole.

A method, a device, and a computer-readable medium for simulating a multilayer optical storage medium are disclosed. A multiple-layer optical storage medium is simulated by using a set of multiple single-layer media, wherein the number of multiple single-layer media is equal to or smaller than the number of multiple layers of the multiple layer optical storage medium, and each single layer of the set of multiple single-layer media comprises a copy of the corresponding layer of the multiple-layer medium. This is transparent to any application software accessing a device having such a single-layer medium inserted therein by the drive reporting to the application that a multi-layer optical storage medium has actually been inserted into the device for reading or writing. The device may be comprised in an audio-visual player and/or a recorder such as a DVD recorder.
摘要:
An optical recording medium having a read-only storage area and a writable storage area and a recording/reproducing apparatus and method therefor. The optical recording medium is a hybrid disc having both the read-only storage area, which is suitable for mass production of information having the same contents, and the writable storage area on which data can be recorded, updated or added at a user's option. The read-only storage area has a structure that is completely compatible with a digital versatile disc read only memory (DVD-ROM) specification, and the writable storage area is compatible with the recording/reproducing characteristics of a writable DVD specification so that an existing reproducing-only apparatus can read information from the read-only storage area, and data can be recorded in the writable storage area using an apparatus obtained by minimally changing an existing recording/reproducing apparatus while maintaining the physical recording characteristics of the existing recording/reproducing apparatus.

A disc drive apparatus includes: a rotational driving unit rotating a disc-shaped recording medium; a recording and/or reproducing unit recording and/or reproducing an information signal on the information recording surface of the disc-shaped recording medium; a print head printing visible information onto a label surface of the disc-shaped recording medium; and a pulse signal generating unit detecting rotation of the rotational driving unit and generating a pulse signal. Further, the apparatus includes a signal processing unit generating a specified address signal where a pulse is generated when a specified address on the disc-shaped recording medium is reproduced; and a control unit carrying out, based on the pulse signal and the specified address signal, disc correlating processing correlating a disc base position where the specified address is recorded on the disc-shaped recording medium and the pulse signal to obtain position information for the disc-shaped recording medium from the pulse signal.

A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. The method for reproducing data of a recording medium using a local storage includes the steps of: a) reading a—binding unit contained in a directory associated with a recording medium from a file structure contained in the local storage/b) performing a binding operation for combining the read binding unit with the file structure contained in the recording medium, and forming a virtual package; and c) reproducing data stored in the recording medium and/or data stored in the local storage using the formed virtual package. Therefore, original data stored in the recording medium and additional data stored in the local storage can be effectively reproduced, resulting in greater convenience of use.
摘要:
Method and recording system for obtaining a data recording on a first medium, such as a DVD, from a data stream originating from a second medium, such as a DV tape. The data stream comprises a number of data segments each having a different recording start time. In the present invention, which may be used ‘on the fly’ and in combination with a pre scan, a recording segment of the data recording on the first medium is generated based on a determination of a duration of a present recording segment. A new recording segment is generated when a recording time discontinuity exceeds a threshold value, the recording time discontinuity being a difference between a recording end time of a first data segment and a recording start time of a next data segment.
摘要:
A method and apparatus for moving copy-once contents to a different recording medium, making it impossible to reproduce information on a write-once recording medium. When copy-once contents recorded on a write-once recording medium are moved to a recording medium which is different from the write-once recording medium, a signal different from that recorded in an information recording area of the write-once recording medium is recorded in the information recording area, thereby making it impossible to reproduce information of the write-once recording medium.
