DAT is used to refer to a certain tape backup format. But in audio/video terminology it normally refers to files that VideoCD has in its SEGMENT or MPEGAV directiories. These DAT files are basically MPEG-1 files with an additional information and certain specific file structure -- they are NOT "real" MPEG-1 files and you need to convert them back to "real" MPEG-1 files in order to edit them even that most of the software players treat them as regular MPEG-1 files.
A helical-scan recording method initially developed to record CD-quality sounds on high-density audio tapes. It was quickly adapted for data storage applications. While DAT cartridges are all the same size (2.1 by 2.9 by 0.4 inches), the properties of the tape inside them differ. The smaller-capacity drives use tape cartridges that can store 1.3GB to 2GB of uncompressed data, and they have typical transfer rates ranging from 183KB per second (KBps) to 366KBps. Their larger-capacity siblings support tape cartridges that store anywhere from 3GB to 4GB of uncompressed data, with typical transfer rates ranging from 366KBps to 510KBps. Many DAT drives offer some type of hardware-based data compression, which can significantly increase capacities and decrease transfer rates, depending on the type of data being stored.
A stereo tape format which records sound in digital code and is smaller in size than an audio cassette. A 4mm DAT drive holds over one gigabyte of data and is used as a high capacity backup medium for computers and as a master source medium for sending data to a CD manufacturer.
(digital audio tape). A system developed initially for recording and playback of digitized audio signals, maintaining signal quality equal to that of a CD. Recent developments in hardware and software might lead to a similar inexpensive system for video archiving, recording and playback.
Digital Audio Tape. Tape which stores data digitally rather than in traditional analogue format. Current DATs use 16-bit word size and 44.1 or 48kHz sample rate giving CD quality. However, shelf life is currently an unknown quantity.
Digital audio tape. A tape technology designed for very-high quality audio recording and data backup. With their 12GB native capacity, DAT data cartridges are most often used for backing up small servers.
Shortened form of Digital Audio Tape. A storage format for audio information on 4mm tape cartridges. Sony originated the techniques for sampling audio data and converting to a digital framework while designing their original DAT drives. These sampling and encoding techniques were than adapted to compact disc.
A magnetic tape technology for backing up data using helical scan recording. DAT uses 4mm cartridges that look like small audiocassettes and conform to the DDS (Digital Data Storage) standard. The DDS standard specifies the format and quality level of DAT technology for computer storage. With capacity points from 4-240GB, DAT or DDS is the industry standard in the workstation, PC and midrange server environments
Digital Audio Tape has gotten its name from the advent of DATs for music. These tapes are really DDT or Digital Data Tapes. Used mainly for long term archives and data storage, this media is slower and is used mainly by system managers.
Stands for Digital Audio Tape. Though the term DAT can apply to any means of digital audio recording, it is generally used to refer to the Japanese 2-track miniature cassette standard for professional and consumer use.
Digital Audio Tape. This format introduced in the late Eighties makes use of a rotating drum containing a helical scan head similar to the sort used in video cassette recorders. Unfortunately disagreement between the recording and hi-fi industries led to a refusal by the major record companies to produce pre-recorded DATs or to sanction the release of a non-copyright protected digital tape recorder hardware. By the time a copyright protection system had been agreed, DAT was dead on its feet as a mainstream consumer format, though it is widely used by professionals and semi-professionals today.
Digital Audio Tape (also R-DAT):. DAT is a system designed for recording and reading digital data using a special tape cassette. DAT can be used to store over one gigabyte of computer data and can be used as a master source medium for sending your audio to MUSIC MANUFACTURING SERVICES for duplication.
16Bit, 48kHz Stereo sound tape that stores music data digitally just like CDs. It is used for higher quality recordings. DAT is not used that much today any more because it is expensive and computer hard disks (for hard-disk recording systems) offer more flexibility for storing such music data.
Digital Audio Tape. DAT recorders, which use a magnetically coded PCM system rather than an optically read one like the compact disc, are divided into two types: RDAT, which has its tape heads attached to a rotating drum to keep linear tape speeds low (the heads are similar to but smaller than those used on video recorders), and SDAT, which uses stationary heads and requires great quantities of tape running at high speed.
A tape technology designed for very high - quality audio recording and data backup. DAT cartridges look like audio cassettes. And they are often used in mechanical auto-loaders. The basic DAT cartri ... more
Digital Audio Tape – Although generally used for audio, a DAT (120 meters long) can hold up to 10 gigabytes if used for digital data storage. Has the disadvantage of being a serial, rather than a random access device.
isaster ction eam. Red Cross volunteers who make the initial response to a disaster scene. Their job is to assess the situation and begin any needed relief. DAT responds to incidents ranging from single family house fires to large-scale emergencies affecting entire communities. Red Cross chapters are assigned blocks of unit numbers to be used on the nationwide 47.42 MHz frequency by the National HQ. Any chapter may operate on this channel. The Monroe County Chapter makes the most consistent use of the radio. Rochester's number block is 1655-1674.
Drug Action Team Drug Action Teams bring together representatives of all the local agencies involved in tackling the misuse of drugs, including the health authority, local authority – social services, education and youth services, police, probation, and the voluntary sector. DATs work with Crime and Disorder Reduction Partnerships.
deposition analysis threshold. a DAT is the additional amount of nitrogen or sulfur deposition within a Class I area, below which estimated impacts from a proposed new or modified source are considered insignificant.
