摘要： A data storage device has associated therewith a removable storage medium. The data storage device has a main control unit with a microprocessor. The system is designed such that an internal control program for control of the media is stored directly on the media itself. By use of a boot program which can be stored in the microprocessor or separately from the microprocessor, the control program is read off of the media by the microprocessor and is stored in a main control program storage within the data storage device. The main control program storage is an erasible storage like an EEPROM, RAM, or flash memory.

摘要： In a magnetic layer storage having a magnetic head positionable relative to a storage medium, a reference storage medium produced with high precision is employed for the individual calibration of the storage tape drive, and particularly a positioner means thereof. This reference storage medium carries a track pattern adapted to the respective application and whose exact position is known. During the test run of each and every individual tape drive, this reference storage medium is read, and the read signals are evaluated in order to identify offset of actual position of the magnetic head from its absolute position defined by the reference storage medium. Individual correction factors can be acquired from the relationship of the absolute position to the actual position, these correction factors being stored in the control electronics and being employed during normal operation for correcting the tolerances of the positioner means or of the magnetic head itself.

摘要： A method for seeking the center of a data track recorded on a magnetic tape using a read head, having an accuracy which is not limited by the stepper mechanism which positions the read head relative to the tape, makes use of the discovery that the fundamental component of tape wander is independent of the tape cartridge vendor and the tape length, and therefore the tape wander can be averaged over an integral number of tape wander periods. In the method, the average output from a read head over an integral number of tape wander periods is found at the lower and upper edges of a data track. The read head output from the center of the track is then measured, and is used to calculate an output change versus head position when the read head is partially in the track. The output change versus head position is then used to scale the lower or upper edge position to a position which would result in an output equal to the output found for the opposite edge, and then the center of the track can be found by dividing the sum of one edge position plus the corrected position for the opposite edge by two.

摘要： A housing of a tape drive is adapted for sideways loading of a cartridge. The cartridge is loaded such that three reference points defining a fixed plane within the housing engages the cartridge in a fixed orientation with respect to a head within the drive. The cartridge is canted after the cartridge is engaged at a first one of the three reference points so as to fixedly engage the cartridge at each of the three reference points.

摘要： An electrostatic discharge noise suppression method and system is disclosed for electronic devices, particularly those connected to data buses. Electrostatic discharge protection is provided by breaking high-frequency ground loops by inserting common mode inductors where they can be most effective-in the DC power supplies themselves, in the DC power connections, or just behind the DC connector in the electronic devices. Saturation of the cores of the common mode inductors is prevented in a preferred way by equalizing supply and return currents in the common mode inductors and by preventing DC ground currents from flowing in a chassis between the power supply and the electronic device.

摘要： In a belt-driven tape cartridge of the type used to store data on a magnetic tape in a high speed data storage and retrieval system, the tape must be maintained at a proper tension within the cartridge so as to maintain the tape taut against the write/read head. Slackness in the tape occurs after a repeated number of changes in the tape transport direction or start/stop events, because the tension experienced by the tape is not the same in both transport directions. In a belt-driven cartridge, the tape tension cannot be directly monitored. A method and apparatus for maintaining tape tension in a belt-driven cartridge are disclosed wherein tape tension is indirectly monitored by non-mechanically monitoring a selected tape characteristic, the characteristic changing as the tape tension changes. If the monitored char,, exceeds a predetermined value, or after the passage of a selected amount of time, when the next reversal of tape transport direction occurs, the tape is moved a selected distance longer than necessary to effect the reversal so that when a desired data location on the tape reaches the location of the write/read head, the tape will again be at the proper tension.

摘要： A drive unit for driving magnetic tape held within a tape cartridge, the tape cartridge engaged to the drive unit in abutting fashion. The drive unit provides an elastomeric drive belt which surrounds a drive pulley, a tensioning pulley and an engagement pulley, the engagement pulley resiliently urging the drive belt against a cartridge roller located within the cartridge which progresses the magnetic tape within the cartridge. The drive pulley is driven directly by motor which progresses the belt around the three rotating pulleys. The arrangement eliminates the need for a separate friction roller arranged above the drive belt by using the drive belt itself to drive the cartridge roller.

摘要： A cleaning cassette has, at one longitudinal side, a cleaning element for cleaning a magnetic head of a magnetic tape recorder, and has a cleaning element at the opposite longitudinal side for cleaning a tape drive roller of the magnetic tape recorder. Dependent on the direction in which the cleaning cassette is introduced into the magnetic tape recorder, the one cleaning element comes into contact with the magnetic head, or the further cleaning element comes into contact with the tape drive roller, for the purpose of cleaning. The magnetic head is cleaned by a reciprocating motion of the cleaning element via an eccentric arrangement effected by the tape drive roller. The cleaning of the tape drive roller upon introduction of the cleaning cassette in an opposite direction occurs due to the rotational motion of the tape drive roller given a stationary, further cleaning element.

摘要： For converting analog signals into binary signals which are respectively allocated to zero axis crossings of the analog signals, the analog signals are first converted into rectangular signals whose binary values change at the zero axis crossings of the analog signals. The rectangular signals are supplied to a delay unit which delays the rectangular signals in steps by a respective time duration which is short in comparison to a shortest period duration of the rectangular signals. Dependent on the various, simultaneously appearing binary values of the delayed rectangular signals, a processing unit generates binary signals which are respectively allocated to a correct zero axis crossing of the analog signals. The processing unit can contain a read-only memory and/or a microprocessor, and can also be fashioned such that it automatically adapts to disturbances present in the analog signals in order to generate correct binary signals, despite these disturbances.

摘要： When setting a write gap or a read gap to a recording track on a magnetic medium, an edge of the medium is selected as a starting point, proceeding from which the write and read means are displaced in fixed track spacings. Appropriate method steps are:(a) generating a write signal with the write means of a read and write system exhibiting a write and a read means;(b) moving the medium from the write means toward the read means;(c) executing a read operation with the read means which generates a read signal;(d) comparing the read signal to a reference value identifying the write signal; and(e) outputting a detector signal indicating the edge when the write signal has been identified.
