  • Patent number: 10026422
    Abstract: A data writer may be configured with a write pole that has one or more sidewalls continuously extending from an air bearing surface. A write pole sidewall can have a plurality of different wall angles. A portion of a write pole sidewall contacting the air bearing surface can have a first wall angle with respect to a trailing edge of the write pole, parallel to the air bearing surface. A second portion of the write pole sidewall can be half or less of the first wall angle. A third portion of the write pole sidewall can be smaller than the second wall angle.

  • Patent number: 9728207
    Abstract: A data storage system may have at least one data writer that incorporates a write pole that continuously extends from an air bearing surface. The write pole can be separated from the air bearing surface by a side shield that consists of a first magnetic layer positioned on the air bearing surface and a guard layer separated from the air bearing surface by the first magnetic layer. The guard layer may be configured with a different magnetic saturation flux density than the first magnetic layer.

  • Patent number: 9437220
    Abstract: A data writing element may be configured at least with a write pole positioned adjacent a first shield along a first axis and adjacent a second shield along a second axis. The second shield may be separated from the write pole by a first gap distance on an air bearing surface (ABS) and by a second gap distance distal the ABS with the first and second gap distances meeting at a transition surface oriented parallel to the ABS.

  • Patent number: 9163255
    Abstract: Polynucleotides isolated from chickpea are disclosed herein. The disclosed polynucleotides of the present invention provide genotype-dependent spatial information on the presence and relative abundance of each gene. The transcriptomic analysis of the polynucleotides revealed (649) non-cannonical genes besides many unexpected candidates with known biochemical functions, which have never been associated with pathostress-responsive transcriptome. The polynucleotides disclosed in the present invention can be used as a molecular tool for isolation of novel genes from plants that can be used for plant improvement. Further, the polynucleotide responsible for improving immunity against fungal pathogen in plants is disclosed herein. The present invention also provides a method of improving immunity against fungal pathogen in plants. Transgenic plants exhibiting improved immunity against fungal pathogen are also provided in the present invention.

  • Patent number: 8649125
    Abstract: The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.
