摘要： A motor vehicle turn signal lamp containing a electronic circuit that fits into a standard automotive turn signal lamp socket without modification, with the added feature that it will stop flashing after a set time even if the driver has forgotten to cancel the turn signal. Special circuitry within the bulb housing allows it to operate uninterrupted on the pulsing, intermittent power normally delivered by an external turn signal system. Because the lamp has the same external size and shape as an ordinary turn signal lamp, the desirable self canceling feature can be added to any vehicle simply by changing out the original lamps and replacing them with the object of this invention.

摘要： A lateral tape sensor for a tape drive having a tape head that is not capable of moving vertically as quickly as tape media, wherein the sensor senses lateral movement of tape media as it moves along a tape path between a storage reel and a take-up reel. The lateral tape motion sensor comprising a means for sensing the position of at least one edge of the tape media and a means for comparing the at least one edge position to predetermined thresholds to determine if the tape media moved laterally. When the lateral movement exceeds predetermined thresholds, the tape drive processor and control circuits respond to prevent accidentally overwriting data previously written on an adjacent track during a write operation, to adjust the tape head to locate data being read following lateral tape motion that occurs during a read operation or to warn the user of poor tape media quality.

摘要： In a helical scan system for recording information on a storage media in a series of helical tracks, servo information written on the tracks is used to control linear velocity of the media during a write operation. Helical scan system includes a rotating drum upon which write heads and read heads circumferentially are mounted. The write heads and the read heads are positioned on the drum so that during a drum revolution a read head reads servo information recorded on a track at least 1.5 track pitches upstream from the most recently recorded track. A servo controller analyzes, during the recording operation, servo information read back by the read head subsequent to recording thereof by write head. Servo controller uses the servo information read by the read head to generate a signal for application to a motor for controlling linear velocity of the media during the write operation.

摘要： A method and system for detecting tape attachment to a machine reel of an automatically threading magnetic tape system. During the threading process, a file reel is rotated to allow a sufficient length of tape to be unwound therefrom, which length of tape eventually attaches to the machine reel after being automatically threaded through the desired tape path. The rotation of the file reel is maintained during this threading process by delivering current pulses to a file reel motor. These current pulses are counted per unit time. As soon as the tape attaches to the machine reel, the machine reel begins to pull the tape from the file reel, thereby eliminating the need to deliver current pulses to the file reel motor, at the same rate as needed prior to tape attachment. A change in the rate of the current pulses delivered to the file reel motor signals a tape attached condition.

摘要： In one example, a dual source tracking servo system includes a head assembly having a data transducer, a primary position detector for sensing the position of a magnetically stored data track, and a secondary position detector for sensing the position of a fixed reference associated with a magnetic storage medium. A controller is configured for adjusting the position of the head assembly in response to a weighted average of the sensed position of the magnetically stored data track and the fixed reference, wherein the position of the magnetically stored data track is weighted more than the position of the fixed reference. The primary position detector may include one or more dedicated servo read elements associated with the head assembly and the secondary position detector may include a magnetic or optical sensor. The fixed reference may include a tape edge or servo track.

摘要： According to the present method a plurality of vertically adjacent reference tracks corresponding to a plurality of vertically adjacent data tracks are written to the tape media so that each data track includes a dedicated reference track that is used to locate that data track. To locate a desired data track, the tape head assembly is used to locate a boundary between a reference track corresponding to a desired data track and an adjacent reference track. Using the boundary as a reference point, the tape head assembly is aligned with the desired reference track and the tape media wound through the tape path to read or right data to the corresponding track.

摘要： The sensing assembly comprises a microprocessor, a cam, and a position sensor that provide feedback on the disconnection status of a buckle between a takeup leader and a tape cartridge leader. The microprocessor uses the position sensor to detect a first position and a second position of the takeup leader in the tape path. The microprocessor uses the movement between the first position and the second position to determine if the takeup leader and the tape cartridge leader are disconnected prior to ejecting the tape cartridge. The cam permits the load motor operation to be briefly paused during the sensing.

摘要： A tracking method enables a first read head (R1) and a second read head (R2) of a helical scan tape drive (30) to read non-native helical stripes, the non-native helical stripes being wider than native stripes. Read signals from the first read head (R1) and the second read (R2) head which are acquired from the non-native tracks are used to determine a correction value. The correction value is in turn used to control a relative position of the first read head (R1) and the second read head (R2) over the non-native helical stripes.

摘要： A data cartridge contains a battery powered clock that can be read by a media drive. The clock's value is written to the tape as a timestamp, and the timestamp is associated with a data set. The drive is designed such that the clock's value cannot be altered by the host system before being written to the tape. For further security, a confirmation value may be generated based upon the data set and the clock's value. The confirmation value is written to the tape in association with the data set and time stamp. Subsequent modification of the data set can be detected by retrieving the confirmation value from the storage medium, calculating a new confirmation value based upon the data set's current contents, and comparing the two confirmation values. If the two values are not equal, then the data set has been modified since the time represented by the timestamp.
