  • Title: QIC - Recovering ".qic" files
    Descriptive info: Recovering.. qic files.. What is a.. qic file?.. A.. qic file is a backup file written in QIC-113 format.. A single.. qic file contains a collection of files, much like a.. zip file.. Backup programs insert files into.. qic files to gain a number of advantages including:.. * Compression, typically cutting storage space for the file in half.. * Spanning, permitting large collections of files to be split across multiple discs.. * Extended attributes, saving long filenames, security, etc.. so the files can be restored on any operating system exactly as they were originally.. How do I extract files from a.. Files can be extracted from a.. qic file using the restore feature of the Windows 95/98 Backup program.. The Backup program can be started from the start menu by selecting Programs - Accessories - System Tools - Backup.. How do I install the Windows 95/98 Backup program?.. The Backup program is an optional accessory and may already be installed.. If not, the Backup program can be installed  ...   What are the limitations of Windows Backup?.. The backup software provided by Microsoft on their Windows operating systems was intended as a simple utility to recover lost data.. It was not designed to do complex backup operations or transport data between different operating systems.. How do I open.. qic files on Windows NT/2000/XP?.. Data sets generated by Windows 95/98/ME backup software are not compatible with Windows 2000 backup software.. To transport data between operating systems, you will need to purchase a product designed for that purpose.. You can use backup software to do that as long as the software that you are using works on both operating systems or writes data in a format that works with other software.. There is backup software available for Windows NT, 2000 and XP that will restore data written in.. qic format that is generated by Windows 95/98/ME backup software.. One such package is Backup MyPC by Roxio, available at.. http://www.. roxio.. com/enu/store/backup.. html.. Home page.. Top of page.. Copyright QIC 2005..

QIC media for the 5.. 25-inch form factor is a data cartridge; QIC media for the 3.. 5-inch form factor is a minicartridge.. coercivity.. the field strength required to change the magnetic state of magnetic material; expressed in Oersteds.. compare.. to verify that a copy of a file is identical to the source.. compression.. (data compression).. an algorithm that reduces redundant strings of data, resulting in decreased file sizes; can be performed by hardware or software - but only one time.. CRC.. (cyclic redundancy check).. a complex mathematical method used to ensure the data written to the tape is error free data cartridge a QIC cartridge that can be used in 5.. 25-inch form factor drives.. data density.. the measure of how much data is stored in a given length of tape or track.. typically expressed in BPI data encryption encoding data for maximum security.. data integrity.. the validity of recorded information.. data transfer rate.. the speed at which data is transferred between a host and a data recording device.. usually noted in bytes/sec or MB/minute.. directory.. an area or data structure in which information is stored regarding the location and contents of files and/or file structures.. also called directory partition.. ECC.. (error correction code).. a mathematical algorithm used to detect and correct errors should they occur.. edge seek.. a method of using the recording head to detect the edge of tape and then to reference the tracks from the edge of tape, thus ensuring accurate track positioning.. embedded OS.. an operating system which is self-contained with hardware and software which forms a component of a larger system and which functions without human intervention.. encoding.. a method whereby a group of data bits is translated into a group of recording bits.. _ GCR.. (group code recording).. a data encoding method often used on several classes of QIC drives.. the code combines high data density with relative ease of decoding.. _ MFM..

MIG heads allow for very high flux densities.. read/write tape speed.. relative head-to-tape velocity during reading and writing.. recording format.. the definition of how data is written to the tape.. it defines such things as the number and position of tracks, bits per inch and the recording code to be used.. redirected restore.. retrieving information from a tape drive into a new logical area.. reference burst.. a number of flux transitions written at the beginning of tape to indicate the center line of the tape.. this information allows the read head of the drive to align itself correctly and improves the data integrity of the drive.. restore.. retrieving information from a tape drive and recording it on a disk drive.. retension.. winding tape from one hub to the other to equalize tape tension.. new tapes and tapes that have been stored or used frequently should be retensioned before use.. RWW.. (read while write).. a method whereby data being recorded are read and verified on the same pass as they are written.. scheduled backup.. backup routine performed at a predetermined time which typically involves taking over the host system; programmed by the software.. search.. locating a data file.. serpentine.. a bi-directional recording scheme; recording of one track in a forward direction is followed by recording the next track in a reverse direction.. servo.. a closed-loop control system used to adjust head position and/or tape speed.. servo burst.. a recorded signal used to control positioning.. streamer.. a device that can transfer data with uninterrupted tape motion.. streaming.. writing or reading blocks without stopping between blocks.. tape catalog.. a listing of files stored on tape.. tape rotation.. a method of backing up information on alternate groups of tapes to ensure an up-to-date copy of all files is on hand.. TB.. (terabyte).. a unit of measure for storage capacity.. 1,000,000,000,000 (1 trillion) bytes,.. or 1,000 (1 thousand) gigabytes.. TPI.. tracks per inch.. tracks/recording tracks.. the narrow strips of media on which data are written.. transfer rate/data transfer rate.. the rate or speed at which information is written to tape, typically expressed in MB/minute or bytes/second.. unattended backup.. backup automatically performed under software/system supervision without the need for human intervention.. underrun.. (buffer underrun).. the condition occurring when the rate at which the data written to tape exceeds the rate at which the host system can transfer data to the tape drive controller.. when the buffer is emptied, the tape drive must stop recording, refill the buffer, reposition the write head with respect to the last data written, and resume writing.. see also overrun.. variable blocks.. data organized into variable-length logical blocks for transmission between devices.. no two blocks are necessarily the same size.. see also fixed blocks.. versioning.. keeping a recording of each of a succession of versions, or revision levels, of a file or document.. verify.. comparing data read to data written.. volume.. a logical division of data.. volume label.. a data block written at the front of a volume to identify it..

  • Title: QIC Technology & Migration Paths
    Descriptive info: TECHNOLOGY.. BRIEF.. Q.. What was the QIC organization?.. (QIC) was an international trade association incorporated in 1987.. It was a direct outgrowth of the Working Group for Quarter-Inch Cartridge Drive Compatibility, also known as QIC, organized in 1982.. The primary purposes of QIC included the promotion of QIC technology among computer users, resellers, dealers, industry analysts, trade and technical press, and the formulation of development standards for compatibility among various manufacturers' drives, cartridges and subsystems.. What is QIC technology?.. QIC technology was developed specifically for data storage applications, and includes the following elements:.. Single-capstan drive units containing magnetic read/write heads and electronics for read/write, motion  ...   up to 1500 feet of quarter-inch magnetic-coated tape, and containing integral tape motion and guidance mechanisms.. Data from computer system hard disks are recorded on up to 144 tracks along the quarter-inch tape in serial, serpentine fashion, with storage capacities currently ranging up to 13 GB (uncompressed.. ).. Menu-driven software, assuring easy backup, archiving or restoration of data.. Are QIC capacities stated in compressed or uncompressed forms?.. All QIC industry capacity references are stated in uncompressed capacities to avoid confusion among users.. Compression can vary with the application, and in some cases provides no increase at all.. Individual company products may specify compressed data capacity..
