On gloss:

cukmakyvelvei
v4=m1=c1 is a computer disk/hard disk/floppy disk storing v2 (data/facts/du'u) about v3 (object/event) in file(s) v1.

In definition:

cukla
x1 is round/circular [2-dimensional shape/form]; x1 is a disk/circle/ring.
jajycukla
x1 is an accretion disk (in astronomy)
jinrcaibyca'u
x1 is a region/room/volume of space which is shaped like a washer (or thin or flattened torus/toroid), between inner disk/sphere x2 and outer disk/sphere x3, defined by midplane x4, and containing x5.
tairbagycukykruca
x1 is the conceptualized/ideal/abstract shape of a biconvex lens formed by/manifested from the intersection x2 (parameters) of two-dimensional circular disks immersed (embedded) in geometry/defined by metric x3; x1 is the convex-only region bounded by intersecting circular arcs given by x2
tairjirnycukykruca
x1 is the conceptualized/ideal/abstract shape of a crescent/concave 'horned' (then convex rounded) form/geometric partially-concave lune formed by/manifested from the intersection x2 (parameters) of two-dimensional circular disks immersed (embedded) in geometry/defined by metric x3
