Disk drive apparatus

A disk drive apparatus comprising:

• a first chassis unit that has a first base chassis and a first pickup base supported by the first base chassis through an elastically deformable insulator;
• and
• a second chassis unit that has a second base chassis and a second pickup base supported by the second base chassis through an elastically deformable insulator,
• wherein, at the first pickup base, arranged are a disk table on which a disk-like recording medium is loaded and a first optical pickup that performs recording or reproduction of an information signal to the disk-like recording medium,
• wherein, at the second pickup base, arranged are a chucking pulley that holds the disk-like recording medium by sandwiching the disk-like recording medium together with the disk table and a second optical pickup that performs recording or reproduction of an information signal to the disk-like recording medium,
• wherein at least one of the first chassis unit and the second chassis unit is moved in a thickness direction of the disk-like recording medium, and the first pickup base and the second pickup base are connected to or separated from each other,
• wherein positioning parts for performing positioning of the first pickup base and the second pickup base at a time of connection are provided at the first pickup base and the second pickup base, respectively, and
• wherein the first pickup base and the second pickup base are connected to each other by magnetic forces of magnets.
