This form factor has proven to work well with stand alone drives and for use in automated tape libraries. Nearly all 1/2" tape formats today are a single hub design, whereby the tape is wound onto a single hub, entirely within the external shell and presents one end for the tape drive to engage and thread into the tape drive for reading or writing.
[1] Oracle StorageTek SL8500 is an enterprise-class robotic tape library. Each library module starts with a capacity of 1448 tape cartridges, and expands in 1728 cartridge increments to a maximum capacity of 10088. [2] It supports up to 64 tape drives and 4 or 8 independent robots in each library. [3]
Oracle's free open source StorageTek Linear Tape File System (LTFS), Open Edition software [10] is claimed to be the first to store 8.5TB (native capacity) on a single cartridge. It supports Oracle’s midrange StorageTek LTO 5 and LTO 6 tape drives from HP and IBM as well as Oracle’s StorageTek T10000C and T10000D tape drives.
In computer science, type conversion, [1] [2] type casting, [1] [3] type coercion, [3] and type juggling [4] [5] are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string , and vice versa.
It was targeted for a mainframe market, where many legacy applications tend to use a lot of very short tape volumes. It used the ESCON interface, and acted as a disk cache for the IBM 3494 tape library. A competitive offering from StorageTek (acquired in 2005 by Sun Microsystems, then subsequently by Oracle Corporation) was known as Virtual ...
Resolution of 1 ps with a 100 MHz (10 ns) clock requires a stretch ratio of 10,000 and implies a conversion time of 150 μs. [13] To decrease the conversion time, the interpolator circuit can be used twice in a residual interpolator technique. [13] The fast ramp is used initially as above to determine the time. The slow ramp is only at 1/100.
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

In the ANSI X3.27-1969 magnetic tape standard, the end of file was indicated by a tape mark, which consisted of a gap of approximately 3.5 inches of tape followed by a single byte containing the character 0x13 (hex) for nine-track tapes and 017 (octal) for seven-track tapes. [5] The end-of-tape, commonly abbreviated as EOT, was indicated by two ...
