  In this work we study an inverse problem for the minimal surface equation on
a Riemannian manifold $(\mathbb{R}^{n},g)$ where the metric is of the form
$g(x)=c(x)(\hat{g}\oplus e)$. Here $\hat{g}$ is a simple Riemannian metric on
$\mathbb{R}^{n-1}$, $e$ is the Euclidean metric on $\mathbb{R}$ and $c$ a
smooth positive function. We show that if we know the associated
Dirichlet-to-Neumann maps corresponding to metrics $g$ and $\tilde{c}g$, then
the Taylor series of the conformal factor $\tilde{c}$ at $x_n=0$ is equal to a
positive constant. We also show a partial data result when $n=3$.
