Abstract
Abstract In a disk unit containing in a predesignated size, an arm, read/write heads secured to an end of arm, a printed circuit board, and leads connecting read/write heads to the printed circuit board, the disk unit of the present invention is realized by: employing a straight-type arm in place of a conventional dog-leg shaped arm; providing a structure for mounting a printed circuit board on a side of the disk unit where a space is made by employing the straight-type arm; moving a printed circuit board conventionally mounted above the disks to the above-mentioned space, thus evacuating the upper part of the disks; and providing additional disks in the above-mentioned evacuated upper part of the disks to increase storage capacity of a disk unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
A disk unit comprising: a disk having a rotational axis thereof; a read/write head, positioned onto said disk, for reading information out and/or writing information on said disk; an arm, connected at one end to a rotational axis and at the other end to said readwrite head, for rotating said read/write head to a desired position of said disk; a printed circuit board; a flexible printed circuit board connecting said read/write head to said printed circuit board, said flexible printed circuit board having a first position extending along said arm and a second position extending away from said arm to said printed circuit board; and diverting means, connected to said arm, for changing said flexible printed circuit board from the first position to the second position and for changing a route the second position follows.
Claim 2
Dependent Claim
135 words
A disk unit comprising: a disk having a rotational axis thereof; a read/write head, positioned onto said disk, for reading information out and/or writing information on said disk; an arm, connected at one end to a rotational axis and at the other end to said readwrite head, for rotating said read/write head to a desired position of said disk; a printed circuit board; a flexible printed circuit board connecting said read/write head to said printed circuit board, said flexible printed circuit board having a first position extending along said arm and a second position extending away from said arm to said printed circuit board; and diverting means, connected to said arm, for changing said flexible printed circuit board from the first position to the second position and for changing a route the second position follows.
Claim 3
Dependent Claim
15 words
A disk unit according to claim 1, wherein said diverting means is an L-shaped fitting.
Claim 4
Dependent Claim
23 words
A disk unit according to claim 2 further comprising a locking plate which presses said flexible printed circuit board against said L-shaped fitting.
Claim 5
Dependent Claim
20 words
A disk unit according to claim 3 further comprising a pin which locks said locking plate to said L-shaped fitting.
Claim 6
Dependent Claim
60 words
A disk unit according to claim 1 further comprising a housing having a wall provided in parallel with the rotational axis of said disk, the wall having a depressed portion, and said printed circuit board connected to said read/write head and located in said depressed portion, said printed circuit board extending in parallel with he rotational axis of said disk.
Claim 7
Dependent Claim
24 words
A disk unit according to claim 5 wherein said printed circuit board mounts circuits which receive and send read/write signals from/to said read/write head.
Claim 8
Dependent Claim
24 words
A disk unit according to claim 5 wherein said diverting means is provided on a side of said arm which faces said depressed portion.
Claim 9
Dependent Claim
25 words
A disk unit according to claim 5 wherein said disk includes a plurality of disks and said read/write head includes a plurality of read/write heads.
