Abstract: A heat pump system includes a heat pump circuit, a heat load circuit, first and second heat exchangers, a flow rate regulation mechanism and a controller. A first passage connects branching and converging portions of the heat load circuit. A second passage connects the branching and converging portions without converging with the first passage. The first and second heat exchanger perform heat exchange between discharge refrigerant from the low and high stage compression mechanisms and fluid in the first and second passages, respectively. The flow rate regulation mechanism regulates a ratio between flow rates through the first and second passages. The controller controls the flow rate regulation mechanism so that the fluid is allowed to flow to the first heat exchanger when a temperature of refrigerant flowing into the first heat exchanger is lower than a heating target temperature of converged fluid flowing through the heat load circuit.

Alternatively, the controller performs distribution control to reduce a difference between the temperatures of the refrigerant discharged from the low-stage and high stage compression mechanisms and after heat exchange with the first and second heat loads, respectively.

Abstract: Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.
