The paper considers the class of Hamiltonian systems with two degrees of freedom. Based on the classical normal form. according to the rules of Born-Jordan and Weyl-MacCoy. its quantum analogs are constructed for which the eigenvalue problem is solved and approximate formulas for the energy spectrum are found. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC550-WUH721816ALE6L0-0F38460-16TB-7-2K-RPM-SATA-6Gb-s-512e-ISE-3-5in-Hard-Drive/
