Media Block Address NOTE 1: This is not to be confused with a logical block address [4/7.1], given by the lb_addr structure which contains both a logical block number [3/8.8.1] and a partition reference number [3/8.8], the latter identifying the partition [3/8.7] which contains the addressed logical block [3/8.8.1]. NOTE 2: A logical block number [3/8.8.1] translates to a logical sector number [3/8.1.2] according to the scheme indicated by the partition map [3/10.7] of the partition [3/8.7], which contains the addressed logical block [3/8.8.1] A sector number [3/8.1.1], derived from the unique sector address given by a relevant standard for recording [1/5.10]. In this specification, a sector number [3/8.1.1] is equivalent to a logical sector number [3/8.1.2]. Packet A recordable unit, which is an integer number of contiguous sectors [1/5.9], which consist of user data sectors, and may include additional sectors [1/5.9] which are recorded as overhead of the Packet-writing operation and are addressable according to the relevant standard for recording [1/5.10]. Physical Address A sector number [3/8.1.1], derived from the unique sector address given by a relevant standard for recording [1/5.10]. In this specification, a sector number [3/8.1.1] is equivalent to a logical sector number [3/8.1.2]. Physical Block Address A sector number [3/8.1.1], derived from the unique sector address given by a relevant standard for recording [1/5.10]. In this specification, a sector number [3/8.1.1] is equivalent to a logical sector number [3/8.1.2]. physical sector A sector [1/5.9] given by a relevant standard for recording [1/5.10]. In this specification, a sector [1/5.9] is equivalent to a a logical sector [3/8.1.2]. Random Access File System A file system for randomly writable media, either write once or rewritable Sequential File System A file system for sequentially written media (e.g. CD-R) Session The tracks of a volume shall be organized into one or more sessions as specified by the Orange Book part-II. A session shall be a sequence of one or more tracks, the track numbers of which form a contiguous ascending sequence. Track The sectors of a volume shall be organized into one or more tracks. A track shall be a sequence of sectors, the sector numbers of which form a contiguous ascending sequence. No sector shall belong to more than one track. UDF Note: There may be gaps between tracks; that is, the last sector of a track need not be adjacent to the first sector of the next track. OSTA Universal Disk Format UDF 2.01 5 March50 April
user data blocks The logical blocks [3/8.8.1] which were recorded in the sectors [1/5.9] (equivalent in this specification to logical sectors [3/8.1.2]) of a Packet and which contain the data intentionally recorded by the user of the drive. This specifically does not include the logical blocks [3/8.8.1], if any, whose constituent sectors [1/5.9] were used for the overhead of recording the Packet, even though those sectors [1/5.9] are addressable according to the relevant standard for recording [1/5.10]. Like any logical blocks [3/8.8.1], user data blocks are identified by logical block numbers [3/8.8.1]. user data sectors Variable Packet Virtual Address virtual partition virtual sector VAT VAT ICB . The sectors [1/5.9] of a Packet which contain the data intentionally recorded by the user of the drive, specifically not including those sectors [1/5.9] used for the overhead of recording the Packet, even though those sectors [1/5.9] may be addressable according to the relevant standard for recording [1/5.10]. Like any sectors [1/5.9], user data sectors are identified by sector numbers [3/8.1.1]. In this specification, a sector number [3/8.1.1] is equivalent to a a logical sector number [3/8.1.2]. An incremental recording method in which each packet in a given track is of a host determined length. Addresses presented to a CD drive are as specified in Method 1 addressing in Orange Book parts II and III. A logical block number [3/8.8.1] of a logical block [3/8.8.1] in a virtual partition. Such a logical block [3/8.8.1] is recorded using the space of a logical block [3/8.8.1] of a corresponding non-virtual partition. The Nth Uint32 in the VAT represents the logical block number [3/8.8.1] in a non-virtual partition used to record logical block number N of its corresponding virtual partition. The first virtual address is 0. A partition of a logical volume [3/8.8] identified in a logical volume descriptor [3/10.6] by a Type 2 partition map [3/10.7.3] recorded according section 2.2.8 of this specification. The virtual partition map contains a partition number that is the same as the partition number [3/10.7.2.4] in a Type 1 partition map [3/10.7.2] in the same logical volume descriptor [3/10.6]. Each logical block [3/8.8.1] in the virtual partition is recorded using the space of a logical block [3/8.8.1] of that corresponding non-virtual partition. A VAT lists the logical blocks [3/8.8.1] of the non-virtual partition, which have been used to record the logical blocks [3/8.8.1] of its corresponding virtual partition. A logical block [3/8.8.1] in a virtual partition. Such a logical block [3/8.8.1] is recorded using the space of a logical block [3/8.8.1] of a corresponding nonvirtual partition. A virtual sector should not be confused with a sector [1/5.9] or a logical sector [3/8.1.2]. A file [4/8.8] recorded in the space of a non-virtual partition which has a corresponding virtual partition, and whose data space [4/8.8.2] is structured according to section 2.2.102.2.11 of this specification. This file provides an ordered list of Uint32s, where the Nth Uint32 represents the logical block number [3/8.8.1] of a non-virtual partition used to record logical block number N of its corresponding virtual partition. This file [4/8.8] is not necessarily referenced by a file identifier descriptor [4/14.4] of a directory [4/8.6] in the file set [4/8.5] of the logical volume [3/8.8]. A File Entry ICB that describes a file containing a Virtual Allocation Table. UDF 2.01 6 March50 April
