 We classify graded simple Jordan superalgebras of growth one which correspond the so called "superconformal algebras" via the TitsKantorKoecher construction. The superconformal algebras with a "hidden" Jordan structure are those of type \(K\) and the recently discovered ChengKac superalgebras \(CK(6)\). We show that Jordan superalgebras related to the type \(K\) are Kantor Doubles of some Jordan brackets on associative commutative superalgebras and list these brackets. Readership Graduate students and research mathematicians interested in nonassociative rings and algebras. Table of Contents  Introduction
