Disk apparatus having magnetic head lifting device

A disk drive adapted to accept and eject a disk cartridge accommodating a disk, comprising:

• a drive base;
• a carriage mounted on said drive base so as to be movable in a radial direction of said disk;
• driving means for moving said carriage;
• a magnetic head assembly mounted on said carriage and having a magnetic head;
• a magnetic head lifter movable between a first position where said magnetic head lifter is engaged with said magnetic head assembly to lift said magnetic head and a second position where said magnetic head lifter is disengaged from said magnetic head assembly;
• biasing means for moving said magnetic head lifter to said first position;
• and
• a solenoid for moving said magnetic head lifter to said second position against a biasing force of said biasing means.

A disk drive adapted to accept and eject a disk cartridge accommodating a disk, comprising:

• a drive base;
• a carriage mounted on said drive base so as to be movable in a radial direction of said disk;
• driving means for moving said carriage;
• a head arm fixed to said carriage;
• a suspension fixed at its base end portion to said head arm;
• a magnetic head mounted on a front end portion of said suspension;
• a permanent magnet fixed to said suspension;
• and
• a solenoid provided so as to be opposed to said permanent magnet, for attracting said permanent magnet by passing a current in a first direction and repelling said permanent magnet by passing a current in a second direction opposite to said first direction.
