28、carrier 11.1 General (see figures 9 and 11) The function of the carrier is to capture and retain the optical disk and to provide the interface to optical disk drives and automated library storage equipment. The carrier shall be capable of supporting and retaining an optical disk while being manipula

29、ted or moved to any position during transportation or storage in a caddy, during load into and unload from a disk drive and while being moved by automated library storage devices. The carrier and optical disk shall be permanently mated and are interchangeable as a sub-assem- bly. The optical disk is

30、 separated from the carrier only when the disk is mounted on the disk drive spindle. The carrier shall provide symmetry for optical disk centreline location regardless of the orienta- tion of the optical disk and carrier sub-assembly in the disk drive. Both the carrier label end and the opposite end

31、 shall be able to be inserted into the storage cells of automated library storage equipment with Side A either up or down. Both the carrier label end and the opposite end shall be able to be inserted into a disk drive incorporated within automated library storage equipment with Side A either up or d

32、own. The carrier shall enable release of the optical disk by the disk drive during loading of the optical disk on to the disk drive spindle. The four carrier latch release holes provide the interface to the disk drive for applying a force F3 to unlatch the carrier and to release the disk. The carrie

33、r latch points, locator pin slots, and latch release holes in conjunction with the disk drives carrier and disk handling devices shall enable the disk drive to maintain a common centreline between the disk and the disk drive spindle during disk release from the carrier and during disk centring and c

34、lamping to the disk drive spindle. The separated carrier and the spindle mounted and clamped optical disk shall allow unobstructed access to the recording zone by a recording head scanning in from the outer edge. The mating carrier shall recapture the optical disk upon dismount of the optical disk f

35、rom the spindle by the disk drive. The carrier label shall indicate the optical disk Side A and Side B and the proper orientation shall be maintained between the optical disk side and the carrier label. The main elements of the carrier are tooth racks. latch points, locator pin slots, Side A and Sid

36、e B hole, write protect holes, latch release holes, disk type sensor notches, and a label area. 11.2 Carrier drawings The carrier is represented schematically by the following drawings: Figure 9 Figure 10 Figure 11 Figure 12 Figure 13 Figure 14 Figure 15 Figure 16 Figure 17 Figure 18 Figure 19 shows

40、en the optical disk side and the carrier label. The Side A of the optical disk shall face downwards when the carrier label Side A is correctly seen when viewed through the caddy window. Reference axes and reference features (see figure 12) Datum A is the top or bottom carrier rail surface. Datum B c

41、onsists of two carrier latch points. Datum C is a carrier locator pin slot. The two carrier latch points at either end of the carrier define the datum B dependent upon which carrier end is inserted first into automated library storage equipment. Any one of the four locator pin slots defines the C da

Mass The mass of the carrier without the optical disk shall not exceed 600 g. Location of the optical disk centre in th

43、e carrier (see figure 10) The carrier shall locate the optical disk centre with respect to the carrier latch points and the carrier locator pin slot as follows: Ll2 = 199.42 mm +_ 051 mm L13 = 112,98 mm f 051 mm Overall dimensions of the carrier (see figure 11) The overall length of the carrier shal
