Recording device, readout device, recording method, recording program, readout method, readout program, and magnetic tape capable of shortening the reading of data recorded on a recording medium
A recording device that generates a hierarchy of groups for classifying each of a plurality of data to be recorded from information on each of the data, and performs a control of recording, for each group of a highest hierarchy, the plurality of data included in the group of the highest hierarchy on a recording medium in a recording order corresponding to an order from the top to the bottom of the hierarchy.
SHORTENING THE AVERAGE REPOSITION TIME TO THE BEGINNING OF FILES IN A MAGNETIC TAPE
A system accesses metadata on a file system of the magnetic tape, where the metadata comprising one or more fields enabling to determine a longitudinal position (LPOS) of one or more files located on the magnetic tape. The system determines the LPOS of the one or more files located on the magnetic tape. The system determines an optimal location of the head on the magnetic tape based on computing an average value to the determined LPOS of the one or more files located on the magnetic tape and moves the head on the magnetic tape to the optimal location.
ERASURE CODING MAGNETIC TAPES FOR MINIMUM LATENCY AND ADAPTIVE PARITY PROTECTION FEEDBACK
A magnetic tape device or system can store erasure encoded data that generates a multi-dimensional erasure code corresponding to an erasure encoded object comprising a code-word (CW). The multi-dimensional erasure code enables using a single magnetic tape in response to a random object/file request, and correct for an error within the single magnetic tape without using other tapes. Encoding logic can further utilize other magnetic tapes to generate additional parity tapes that recover data from an error of the single magnetic tape in response to the error satisfying a threshold severity for a reconstruction of the erasure coded object or chunk(s) of the CW. The encoding logic can be controlled, at least in part, by one or more iterative coding processes between multiple erasure code dimensions that are orthogonal to one another.
APPARATUS AND METHOD FOR PROVIDING INFORMATION IN CONJUNCTION WITH MEDIA CONTENT
An apparatus and method for providing information in conjunction with media content, including a receiver, wherein the receiver receives at least one of a transmission of media content and a broadcast of media content, wherein the media content includes at least one of broadcast media content and entertainment media content, and further wherein the receiver receives information regarding the media content, a processor for processing at least one of the received media content and the received information regarding the media content, a display device for visually displaying the information regarding the media content, and/or a speaker device for audibly announcing the information regarding the media content.
Increasing data storage capacity by reducing index entries
A tape method, according to one embodiment, includes: adjusting a position of a tape head in the tape drive relative to a magnetic tape such that the tape head is positioned at an accumulating backhitchless flush (ABF) wrap on the magnetic tape. A first index is also written in the ABF wrap. The first index corresponds to data written in a data partition on the magnetic tape, and the ABF wrap and the data partition are different partitions. Furthermore, in response to writing the first index in the ABF wrap, the position of the tape head is adjusted relative to the magnetic tape such that the tape head is positioned at the data partition. A first empty index is also appended to an end of the data written in the data partition, where a size of the first empty index is less than a size of the first index.
COPYING FRAGMENTED FILES BETWEEN SEQUENTIAL STORAGE MEDIUMS
A computer-implemented method, according to one embodiment, includes: sending one or more instructions to calculate a combined size of fragments included in the fragmented files, sending one or more instructions to designate a portion of cache which corresponds to at least the combined size of the fragments, sending one or more instructions to send a copy of each non-fragmented file from a first drive directly to a second drive in which the second sequential storage medium is loaded, sending one or more instructions to use the designated portion of the cache to accumulate the fragments included in the fragmented files, and sending one or more instructions to send a copy of each of the fragments corresponding to a given fragmented file from the cache to the second drive in response to determining that all of the fragments corresponding to the given fragmented file have been accumulated in the cache.
MANAGING READ/WRITE COMPATIBILITY BETWEEN STORAGE DEVICES AND STORAGE MEDIA
A tape library storage system, keeps track of the identity(ies) of the drive unit(s) that write upon the storage medium of each tape cartridge, and associates the drive unit identity information with the data that each drive writes. The system writes the associated identity information in the tape cartridge memory and/or inserts the information in an index and writes the index on the tape. If a read error occurs when attempting to read data from the tape, the system, by reference to the associated identity information, determines the identity of the original tape drive that had written the data, and transfers the cartridge to the original drive to attempt again to read the data.
Adaptive pattern recognition based control system and method
An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.
Method and system for conducting business in a transnational E-commerce network
The invention presents a method and system for processing the purchase of products, goods and/or services, more particularly, to a method and system for processing the purchase by a buyer of products from one or more sellers of products in an on-line real-time e-Commerce business environment where the merchant server from which the goods are purchased lacks adequate encryption security for the purchasing of the goods by credit card. The method and system also allows for the easy up-dating registration by a merchant of the items available for purchase as maintained on the Web, DB server. The invention also discloses a method and system for avoiding the hindrance of foreign exchange rates fluctuations on the payment of on-line real-time e-Commerce trading. The system provides for a splitting of a merchant server into a Web, DB server and a payment server, the payment server being located in a nation state to which a purchaser may securely transmit encrypted credit card information in order to purchase product available on websites maintained on the Web, DB server.
Minimizing high resolution tape directory recovery time
Provided is a system, method, and computer program product for minimizing high resolution tape directory (HRTD) recovery time when a HRTD is invalid. A tape drive may load a tape in the tape drive. In response to receiving a write command or a read command at a beginning of tape (BOT) position, the tape drive may execute the write command or the read command without performing HRTD recovery. In response to receiving the write command or the read command at a position other than the BOT position, the tape drive may determine if the HRTD is valid. In response to determining the HRTD is not valid, the tape drive may clear a timer.
