摘要： A novel method is disclosed for performing a high speed search for a selected data block or data file utilizing any one of several presently existing helical scan tape formats which utilize, in addition to the helically scanned tracks, one or more longitudinal tracks for recording indexing information indicative of the location of data blocks and file marks stored on the associated helical tracks. Data file location information is written to a header area on a series of helical tracks and to one (or more) of the longitudinal tracks when a data block or a file mark is written to a tape. A high speed search for a desired data block or data file can then be performed using this track location information.

摘要： The control software and hardware in the tape drive control unit creates and manages a header segment at the beginning of the magnetic tape. This header is interposed between a leader portion of the magnetic tape on the 3480-type cartridge and the remainder of the magnetic tape contained therein. This header segment contains two sections, a first of which is a data record directory that is used by the control unit to denote the location of each data record written on to the magnetic tape as well as administrative information associated with the data record. The second section of the header is an administrative information section that contains data relating to the magnetic tape itself. The stream of data records is divided into data segments, a plurality of which comprise a single helical scan track. The helical scan tracks are formed into scan groups and written on the magnetic tape. At least one longitudinal track is written on the magnetic tape coextensive with the helical scan groups to provide data to enable the tape drive to quickly locate data records recorded on the magnetic tape.

摘要： A helical scan transport apparatus for reading and writing data on to a magnetic recording tape which is wound on a supply reel rotatably mounted within a removable tape cartridge includes a chassis having a front end portion and rear end portion. An elevator assembly is mounted on the chassis at the front end. The elevator assembly is configured to receive the tape cartridge and to position the tape cartridge in a loaded position. A take-up reel assembly is coupled to the chassis at the rear end position. A helical deck is mounted on a central portion of the chassis between the elevator assembly and the take-up reel assembly. The helical deck includes a rotary read/write head, a substantially linear tape loading path between the elevator assembly and the take-up reel assembly, and a movable guide for the seizing the tape from the tape loading path and for at least partially wrapping the tape around the rotary head. A linear threading mechanism is configured to grasp the leader block of the tape, thread the tape through the tape loading path of the helical deck, and couple the leader block to the take-up reel assembly. The helical transport has a form factor compatible with the Storage Technology Corporation Model 4400 Automated Cartridge System.

摘要： In a machine having a reciprocating original document handling carriage such as a copier, a roller at the bottom of a sloped ramp rests on the upper surface of the carriage. Documents placed on the ramp slide downward until the leading edge is at the nip between the roller and carriage surface. Movement of the carriage pulls the document from the tray onto the carriage surface for scanning. An additional roller can be included to provide automatic document ejection by pushing the document onto an output tray as the carriage returns.

摘要： An apparatus for reducing head wear in a helical scan tape transport passes a flow of relatively clean, dry air through a transport housing without allowing the flow of air to flow directly across the rotary head assembly. Air from a fan positioned at a rear portion of the transport cools a power supply and creates a positive air pressure within the transport housing. The air is heated by the power supply before it passes through the transport housing, so that only relatively "dry" air reaches the rotary head assembly. The air is exhausted out the opening through which a tape is loaded. This arrangement substantially reduces the possibility of contaminants entering the transport housing. Additionally, the air cleans a magnetic recording tape on a tape cartridge as the tape is passes through the transport housing so that only relatively "clean" tape reaches the rotary head assembly.

摘要： The cleaning tape comprises a substrate on which is overlaid a coating that provides a mechanical abrading surface to clean the elements in the tape path, such as the read/write heads. The coating has a high coefficient of friction to remove and retain the residues that have accumulated on the read/write heads. The coating is impregnated with or encloses a cleaning solvent that is controllably released by the mechanical movement of the cleaning tape over the read/write heads. The cleaning solvent can be isopropyl alcohol or other solvents that are encapsulated in some manner in the cleaning tape. As the solvent is released on to the read/write heads, it chemically loosens the debris which the abrasive coating can then mechanically remove from the read/write heads and also retain on the abrasive coating.
