  • Publication number: 20230223043
    Abstract: The present disclosure generally relates to a tape head of a tape drive, and methods of forming thereof. In one embodiment, a tape head for magnetic storage devices comprises a trailing shield, a leading shield, a first write pole coupled to the trailing shield, a second write pole coupled to the leading shield, and side shields spaced from the first write pole and the second write pole by a thin insulation layer. The side shields are further disposed between the trailing shield and the leading shield. In another embodiment, a tape head for magnetic storage devices comprises a main pole disposed between a trailing shield and a leading shield and a side shield disposed adjacent to the main pole. The side shield is further disposed between the trailing shield and the leading shield and spaced from the main pole by a thin insulation layer.

  • Patent number: 11681753
    Abstract: A geotagged video spatial indexing method for video retrieval based on a two-dimensional (2D) temporal grid is disclosed and includes: generating the 2D temporal grid by using the earliest start time, the latest end time of all geotagged video clips and a temporal resolution; calculating row and column number information of each geotagged video clip based on its start time and end time; generating a spatial point for each geotagged video clip based on the row and column number information and obtaining a spatial point set; generating a R-tree spatial index structure corresponding to the spatial point set using a R-tree spatial index method; and locating the corresponding cell in a temporal grid based on retrieval conditions, generating a spatial point based on row and column number information of the grid cell, and finding the spatial point in the R-tree spatial index structure to get the geotagged video corresponding thereto.

  • Publication number: 20230186946
    Abstract: The present disclosure is generally related to a tape drive including a tape head configured to read shingled data on a tape. The tape head comprises a first module head assembly aligned with a second module head assembly. Both the first and second module head assemblies comprises a plurality of data heads. Each data head comprises a write head, a first read head aligned with the write head, a second read head offset from the first read head in both a cross-track direction and a down-track direction, and a third read head offset from the first and/or second read heads in the cross-track and down-track directions. By utilizing three read heads within each data head, data can be read from a tape that has experienced tape dimensional stability, as at least one read head will be near a center of each data track of the tape.

  • Patent number: 10408855
    Abstract: Aspects of the disclosure provide a system for detecting a movement that includes a moving state detector, a profile-based movement state detector, and a refined movement state detector. The moving state detector is configured to generate a moving state based on a detected speed. The profile-based movement state detector is configured to determine an estimated movement state based on the moving state and detected accelerations. The refined movement state detector is configured to generate, in response to the estimated movement state corresponding to a predetermined triggering movement state, a refined movement state based on a detected angular velocity.
