Presented herein is a stage area for 'focused' video that is configured to allow for dynamic layout changes during an online video conference or meeting. By providing a user interface environment that allows a user (meeting participant) to customize the stage, each participant can choose their own view, and the meeting host can fully customize a view for every participant in the meeting.

Dynamic video layout design during online meetings

An apparatus may include a composite soft underlayer and a perpendicular magnetic recording layer overlying the composite soft underlayer. The composite soft underlayer may include a growth template layer, a negative magnetic anisotropy layer overlying the growth template layer, and a magnetically soft layer overlying the negative magnetic anisotropy layer. In some embodiments, the negative magnetic anisotropy layer includes a plurality of grains, and substantially all the grains have negative magnetic anisotropy along an axis substantially perpendicular to a major plane of the composite soft underlayer. In some embodiments, the negative magnetic anisotropy layer includes a thickness of less than or equal to about 3 nm.

A magnetic disk media is physically preformatted to have a non-user data area providing any of a servo pattern, a gray code pattern and a timing line pattern. The non-user data area patterns are preformatted to have non-recordable regions with a radial width that is always less than the track pitch of the data area. In exemplary implementations, servo patterns, gray code patterns and timing line patterns are physically preformatted to have a recordable:non-recordable radial width ratio substantially equal to that of a user data area. In certain embodiments, non-magnetic or magnetically suppressed regions having cross-track dimension substantially equal to that of spaces between tracks in the user data area are consecutively offset in a cross-track direction from the discrete track recording pattern of the user data area.

A disk drive with DTR media and method of assembly is described. The method may include aligning a discrete track recording (DTR) track pattern center on a DTR disk with a rotational center of a spindle hub and mounting the DTR disk on the spindle hub to minimize eccentricity. After the DTR disk is mounted to the spindle hub, it may be rotated to a designed rotational speed and the mass imbalance of the rotating DTR disk/spindle hub may be measured. The mass imbalance may be mitigated using a mechanical component such as a counter weight coupled to a spindle rotatable component, for example, the spindle hub, a spacer assembly, a clamp assembly, etc. The method may mitigate the eccentricity associated with DTR media and minimize run-out due to the mass imbalance of an otherwise rotated DTR disk/hub aligned for eccentricity correction.
