Disk device with vibration-insulating mechanism

A disk device comprising:

• a spindle motor for rotating a disk;
• a head for reading and writing information signals relative to said disk;
• a feed mechanism for moving said head radially of said disk;
• a mechanism chassis having said spindle motor, said head and the feed mechanism mounted thereon;
• a cartridge loading mechanism including a cartridge holder for holding a cartridge containing the disk, and a slider disposed reciprocally slidable in a direction of insertion of said cartridge, said cartridge loading mechanism for loading a cartridge, held in said mechanism chassis, into a predetermined position of said mechanism chassis;
• and a casing for mounting said mechanism chassis thereon through vibration-insulating members,
• wherein when said cartridge is to be loaded into the predetermined position of said mechanism chassis and in a state capable of recording and/or reproducing information signals, said cartridge holder is separated from an upper wall of said casing, and said mechanism chassis is in a state of being supported by said vibration-insulating members so as to prevent transmitting of vibration, and when said cartridge is transferred from said state of being supported by said vibration-insulating members to a state of capable of being discharged from and inserted into the disk device, after said cartridge holder is moved toward the upper wall of said casing in accordance with a movement of said slider and prevented from movement thereof by the casing, said mechanism chassis is moved toward a lower wall of said casing by the movement of said slider so as to make said vibration-insulating members more compressed than when in a state of capable of recording and/or reproducing said information signals;
• and
• wherein when said disk device is changed from the state of capable of recording and/or reproducing the information signals to a state of capable of discharging said cartridge from and inserting it into the disk device, the amount of a movement of said cartridge holder toward said casing is substantially equal to the amount of a movement of said mechanism chassis toward the vibration-insulating members.
