US 5,859,750 A · Magnetic recording-and-reproducing apparatus

Abstract

A lower magnetic head is attached to a carriage and a head support member supporting an upper magnetic head is hinged to the carriage. The head support member is provided on its lower surface in a continuous arrangement with a first flat portion, an inclined portion and a second flat portion. A cartridge holder for holding a disk cartridge, and a cross plate are fixed to an open upper end of a main chassis. A driving pin is fixed to the cross plate. When the carriage is moved away from a magnetic disk with an auxiliary chassis held at an upper loading position, the driving pin comes into contact wit the second flat portion of the head support member to separate the upper magnetic head from the magnetic disk. When the carriage moves toward the center of the magnetic disk, the driving pin is disengaged from the head support member, so that the upper magnetic head is pressed through the magnetic disk against the lower magnetic disk.

Dependent claims

A magnetic recording-and-reproducing apparatus comprising:

a main chassis;
an auxiliary chassis having a head moving mechanism including magnetic heads for recording information on and reproducing information from a magnetic disk;
a cam mechanism which positions the auxiliary chassis at a raised load position under a forward movement of the auxiliary chassis on the main chassis and which positions the auxiliary chassis at a lowered unload position under a rearward movement of the auxiliary chassis on the main chassis;
and a cartridge holder fixed to the main chassis to hold a disk cartridge containing a magnetic disk;
wherein the head moving mechanism comprises a carriage supporting one of the magnetic heads and capable of being reciprocated radially of the magnetic disk, and a head support member hinged to the carriage, supporting the other magnetic head, and having an inclined portion;
and the main chassis is provided with a driving member capable of engaging with the inclined portion of the head support member.
