摘要： A disk-drive-compatible magnetic tape cartridge is provided with a tape guide for accurately positioning a magnetic tape in relation to a disk drive head. The tape guide includes a positioning section to be aligned with a rotation axis of a center core assembly when the center core assembly is chucked on a turntable of the disk drive. The tape guide also includes a guide section defining a tape run path across the disk drive head. The guide section is formed integrally with the section to be aligned with the center core assembly and so distanced from the latter as to accurately position the magnetic tape with respect to the disk drive head. Since the tape guide has the positioning section and guide section integrally, the distance therebetween can be maintained precisely constant. Therefore, tracking by the disk drive head becomes easier to allow high-density recording.

摘要： A tape cartridge adapted to utilize the read/write head(s) in a disc drive to read data from and/or write data to the tape. The tape cartridge has a section A having a size and shape which enables it to be inserted into the disc drive to locate a portion of the tape at a location L suitable for transferring data with the disc drive head(s). The tape cartridge includes: tape media; a means to register the tape media with respect to the read/write head(s) of a disc drive; a means for storing that portion of the tape media which is not contained within section A; and a means for feeding the tape media past the read/write head(s) in the disc drive. The tape cartridge may include a linkage that enables it to utilize the disc drive spindle motor to feed the tape. The linkage can also include a clutch to enable tape feed direction to be reversed.

摘要： An apparatus providing the capability to scan media at different resolutions is presented. The apparatus comprises an image area which is disposed between scanner lid and a scanner base, the lid is pivotally attached to the base to provide easy access to the image area. A light source resides within the scanner lid. Two separate light paths are provided, the first light path is reflected off opaque targets, through the lid before entering the base and onto an array of photosensitive devices. The second light path is passed through transparent media, into the base and onto the array. First and second focusing lenses are provided, each for a light path. The focusing lenses provide two separate magnifications which yield two separate resolutions.

摘要： An improved auto-focus system for a digital camera has a lens designed to have the focus of two spectra offset from each other by a predetermined amount. The two offset spectra are used to calculate two focus signals. Once the two focus signals are calculated the correct direction to move the lens system to set the optimum focus can be determined.

摘要： The electrical drive pulse applied to the piezoelectric crystal of an ink jet printer is designed to cause ejection of a single desired ink droplet from the print head and to preclude ejection of unwanted multiple ink droplets. The drive pulse consists of the superposition of two waveforms wherein the first waveform causes ejection of the desired ink droplet and the superimposed second waveform removes energy from the print head so that mechanical ringing of the ink supply within the print head does not cause ejection of unwanted ink droplets.
