  • Patent number: 11972783
    Abstract: In one general embodiment, a data storage product includes a magnetic recording tape having written thereon at least two servo tracks extending along a longitudinal axis of the tape. Each servo track has a timing-based servo (TBS) pattern comprising a series of servo frames arranged to enable lateral positioning of a magnetic head relative to the servo tracks as well as tape dimensional stability (TDS) compensation via head skew. Each frame comprises a sequence of pairs of leading and trailing servo stripes. Midpoints between the servo stripes in each pair, at all points having a same relative lateral height on the tape, are located along a virtual median line oriented at an angle ? from perpendicular to the longitudinal axis of the tape, the angle ? being greater than 1 degree.

  • Publication number: 20220126365
    Abstract: A manufacturing method includes providing a material that includes a plurality of particles and a binder that is uncured. The method also includes forming a first article from the material including curing the binder to bind a collection of the particles together into the first article. Furthermore, the method includes encasing at least a portion of the first article with an outer member. The outer member defines an internal cavity that corresponds to the first article. Additionally, the method includes heating the outer member and the first article to melt the collection of particles into a molten mass within the internal cavity of the outer member. Moreover, the method includes solidifying the molten mass within the outer member to form a second article. The second article corresponds to at least a portion of the internal cavity of the outer member.

  • Patent number: 11145323
    Abstract: A computer-implemented method, according to one embodiment, includes: receiving a first timestamp in response to a first servo reader detecting a stripe of a first servo burst on the magnetic tape, and receiving a second timestamp in response to a second servo reader detecting a stripe of a second servo burst on the magnetic tape. A third timestamp is received in response to the first servo reader detecting a stripe of a third servo burst on the magnetic tape, while a fourth timestamp is received in response to the second servo reader detecting a stripe of a fourth servo burst on the magnetic tape. The first, second, third, and fourth timestamps are used to determine the skew of the magnetic tape. Further still, the first and third servo bursts are in a same first servo sub-frame, while the second and fourth servo bursts are in a same second servo sub-frame.

  • Publication number: 20210230023
    Abstract: A desalination apparatus is disclosed which comprises: a first tank for storing seawater to be desalinated; a second tank comprising a hydrophobic membrane desalination module operable to absorb only fresh water vapors and reject salt components when the seawater is heated to a first predetermined temperature that changes the seawater into the fresh water vapors, and wherein the hydrophobic membrane desalination module is configured to continuously allow the distilled fresh water to make contact with the fresh water vapors within its interior hollow volume; and a third tank, in fluid communication with the second tank, configured to cause the fresh water vapors from the hydrophobic membrane desalination module to be condensed into liquid fresh water by continuously allowing the fresh water vapors to make contact with a coolant water at a second temperature.

  • Patent number: 11011198
    Abstract: A tape drive may arrange timing-based-servo marks into a timing-based-servo pattern. The timing-based-servo pattern may be at least one M-pattern. The tape drive may select the at least one M-pattern. The tape drive may match at least two timing-based-servo marks in the at least one M-pattern. The tape drive may determine, from the matching, whether an alignment of the at least two timing-based-servo marks is demonstrative of tape-creep.

  • Patent number: 10930309
    Abstract: A tape drive may calculate the slopes for three successive timing-based-servo marks in a timing-based-servo group. The timing-based-servo marks may be arranged in a one or more M-patterns. The three successive timing-based-servo marks may be across the one or more M-patterns. The tape drive may perform a parabolic fit of a gradient of the slopes. The tape drive may determine whether the gradient is demonstrative of tape-creep.
