      voltages, which can be used to represent sounds, images,
      or binary data. devices such as audio casette recorders,

magnetic tape
     
         or "magtape", "tape" - paper tape is now
        obsolete a data storage medium consisting of a magnetisable
        oxide coating on a thin plastic strip, commonly used for
        backup and archiving.
     
        early industry-standard magnetic tape was half an inch wide
        and wound on removable reels 10.5 inches in diameter.
        different lengths were available with 2400 feet and 4800 feet
        being common.  dectape was a variation on this "round
        tape".
     
        in modern magnetic tape systems the reels are much smaller and
        are fixed inside a cartridge to protect the tape and for
        ease of handling "square tape" - though it's really
        rectangular.  cartridge formats include qic, dat, and
        exabyte.
     
        tape is read and written on a tape drive or "deck" which
        winds the tape from one reel to the other causing it to move
        past a read/write head.  early tape had seven parallel tracks
        of data along the length of the tape allowing six bit
        characters plus parity written across the tape.  a typical
        recording density was 556 characters per inch.  the tape had
        reflective marks near its end which signaled beginning of tape
        bot and end of tape eot to the hardware.
     
        data is written to tape in blocks with inter-block gaps
        between them.  each block is typically written in a single
        operation with the tape running continuously during the write.
        the larger the block the larger the data buffer required in
        order to supply or receive the data written to or read from
        the tape.  the smaller the block the more tape is wasted as
        inter-block gaps.  several logical records may be combined
        into one physical block to reduce wastage "blocked
        records".  finding a certain block on the tape generally
        involved reading sequentially from the beginning, in contrast
        to magnetic disks.  tape is not suitable for random
        access.  the exception to this is that some systems allow
        tape marks to be written which can be detected while winding
        the tape forward or rewinding it at high speed.  these are
        typically used to separate logical files on a tape.
     
        most tape drives now include some kind of data compression.
        there are several algorithms which provide similar results:
        lz most, idrc exabyte, aldc ibm, qic and
        dlz1 dlt.

        spool, macrotape, microtape, non return to zero
        inverted, phase encoded.
