2、 history Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC toward the development of International Standards for 80 mm, 90 mm, 120 mm, 130 mm
3、, 300 mm, and 356 mm media. Numerous standards have been developed by TC31 and published by Ecma, almost all of which have also been adopted by ISO/IEC under the fast-track procedure. In February 1997 a group of ten Companies, known as the DVD Forum, proposed to TC31 to develop standards for the opt
4、ical disks known as DVD disks. TC31 accepted this proposal and started the work that has led to two Ecma Standards that have been adopted by ISO/IEC under the fast-track procedure as International Standards.

6、SO/IEC 16825 A new Standard ECMA-330 constituting a further development of Standard ECMA-272 proposed to, and accepted by, Ecma/TC31 on presentation by Toshiba Corporation on behalf of ten other Member Companies of the DVD Forum has been undertaken by Ecma/TC31. The development of the present Standa
7、rd ECMA-331 was also proposed and accepted at the same time. It shall specify a case for use with the disks specified in Standard ECMA-330 so as to form an optical disk cartridge. Several Types are specified that allow meeting the requirements of different applications for which such cartridges are
8、used. This Ecma Standard has been adopted by the General Assembly of June 2004.

The present Ecma Standard specifies nine related, but different
29、 implementations of this case, viz. Type 1 A case for a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk such that the disk cannot be removed from the case. This case is reversible. Type 2 A case for a one-sided (Type 1S) 120 mm DVD-RAM disk such that the disk may be removed from the
30、 case. This case is not reversible. Type 3 A case into which a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk may be inserted, then used as a cartridge. This case is not reversible. Type 4 A case for a two-sided (Type 2S) 120 mm DVD-RAM disk such that the disk may be removed from t
31、he case. This case is reversible. Type 5 A case into which a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk may be inserted, then used as a cartridge. This case is reversible. Type 6 A case for a two-sided (Type 2S) 80 mm DVD-RAM disk such that the disk may be removed from the case
32、. This case is reversible. Type 7 A case for a one-sided (Type 1S) 80 mm DVD-RAM disk such that the disk may be removed from the case. This case is not reversible. Type 8 A case into which a two-sided (Type 2S) 80 mm DVD-RAM disk may be inserted, then used as a cartridge. This case is reversible. Ty
33、pe 9 A case into which a one-sided (Type 1S) 80 mm DVD-RAM disk may be inserted, then used as a cartridge. This case is not reversible. This Ecma Standard specifies the environments in which the cases are to be operated and stored; the dimensional and mechanical characteristics of the case, so as to
34、 provide mechanical interchangeability between data processing systems. This Ecma Standard provides for mechanical interchange between optical disk drives. Together with Standard ECMA-330 for 120 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per side) DVD-RAM disks and a standard for volume and fi
35、le structure, it provides for full data interchange between data processing systems. 2 Conformance A claim of conformance with this Ecma Standard shall specify the Type implemented. A case shall be in conformance with this Ecma Standard if it meets the mandatory requirements specified herein for its
36、 Type. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ECMA-330 (2002) 120
37、 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per side) DVD Rewritable Disk (DVD-RAM) ECMA-287 (2002) Safety of electronic equipment - 2 - 4 Definitions For the purpose of this Ecma Standard the following definitions apply: 4.1 Cartridge A device consisting of a case containing a rewritable disk.
38、 4.2 Case The housing for an optical disk, that protects the disk and facilitates disk interchange. 5 Conventions and notations 5.1 Representation of numbers A measured value is rounded off to the least significant digit of the corresponding specified value. For instance, it implies that a specified
39、 value of 1,26 with a positive tolerance of + 0,01 and a negative tolerance of - 0,02 allows a range of measured values from 1,235 to 1,275. 5.2 Names The names of entities, e.g. specific sides, etc. are given a capital initial. 6 General description of the case 6.1 General description of the Type 1
40、 case (Figure 1) The case is a rigid protective container of rectangular shape. Sides A and B of the case are identical as far as the features given here are concerned. References to Sides A and B of the case can be changed to B or A, respectively. When the opening of the one is a head and spindle w
41、indow for the spindle and the optical head of the drive, that of the other is an access window for the disk clamping apparatus. A shutter uncovers the windows upon insertion into the drive, and automatically covers them upon removal from the drive. The case has features that enable a drive to reject
42、 a mis-inserted cartridge, to inhibit writing, sensor holes, detents for autoloading and a vertical use, gripper slots for an autochanger, label areas and side identification marks. Sides A and B of the case have the same configuration. 6.2 General description of the Type 2 case (Figure 2) The Type
43、2 case has the same features as the Type 1 case, but with some differences. The shape of the case is different on Side A and on Side B. Side A does not need to have a location hole, an alignment hole, Reference Surfaces, a write-inhibit hole, sensor holes and sensing areas. The case has an opening c
44、losed by a cover. This cover can be opened. In open position, the disk can be taken out of the case. Sensor hole A1 is originally closed. If the disk has been removed from the case, then this hole remains permanently open, indicating that the original disk contained in the case has been removed at l
45、east once or has been replaced by another disk. 6.3 General description of the Type 3 case (Figure 2) The Type 3 case is identical with Type 2 case except that the sensor hole A1 is always open.

The case has an opening closed by a cover. This cover can be opened. In open position, the disk can be taken out of the case. If the
49、disk has been removed from the case, then the sensor hole A1 and B1 remain permanently open, indicating that the original disk contained in the case has been removed at least once or has been replaced by another disk. - 4 - 6.5 General description of the Type 5 case (Figure 3) The Type 5 case is identical with Type 4 case except that the sensor hole A1 and B1 are always open. for disk Side Bfor disk Side BEdge for shutter openerShutterCase Side ADisk Side BDetent for vertical useOpening coverSensing areaGripper slotAlignment holeLabel areaLocation holeSensor holesWrite-inhib
