  We study the set $M_\infty(X)$ of all infinite full non-atomic Borel measures
on a Cantor space X. For a measure $\mu$ from $M_\infty(X)$ we define a
defective set $M_\mu = \{x \in X : for any clopen set U which contains x we
have \mu(U) = \infty \}$. We call a measure $\mu$ from $M_\infty(X)$
non-defective ($\mu \in M_\infty^0(X)$) if $\mu(M_\mu) = 0$. The paper is
devoted to the classification of measures $\mu$ from $M_\infty^0(X)$ with
respect to a homeomorphism. The notions of goodness and clopen values set
$S(\mu)$ are defined for a non-defective measure $\mu$. We give a criterion
when two good non-defective measures are homeomorphic and prove that there
exist continuum classes of weakly homeomorphic good non-defective measures on a
Cantor space. For any group-like subset $D \subset [0,\infty)$ we find a good
non-defective measure $\mu$ on a Cantor space X with $S(\mu) = D$ and an
aperiodic homeomorphism of X which preserves $\mu$. The set $S$ of infinite
ergodic R-invariant measures on non-simple stationary Bratteli diagrams
consists of non-defective measures. For $\mu \in S$ the set $S(\mu)$ is
group-like, a criterion of goodness is proved for such measures. We show that a
homeomorphism class of a good measure from $S$ contains countably many distinct
good measures from $S$.
