Overview
IEC 62403:2005 - High density recording format on CD‑R/RW disc systems (HD‑BURN format) specifies the HD‑BURN format for CD‑R and CD‑RW media. The HD‑BURN system enables recording at double the data density of conventional CD‑R/RW discs, targeting high reliability, high speed and interchangeability for cost‑sensitive consumer applications. The standard defines the physical recording and playback characteristics, on‑disc track and data structures, and the logical format used to organise recorded information.
Key Topics
The standard covers technical requirements and structures needed to implement HD‑BURN on optical discs, including:
- Physical characteristics for recording and playback: optical and mechanical parameters required for compatible read/write behaviour on CD‑R and CD‑RW media.
- Track and sector structure: layout of tracks, physical sectors (PSN), sector numbering and session/lead‑in/lead‑out arrangements.
- Data frame and ECC formats: channel framing, synchronization frames and use of error correction (including Reed‑Solomon product code - RSPC) to maintain data integrity at higher density.
- Pre‑groove and ATIP: guidance track encoding, ATIP (absolute time in pre‑groove) and related synchronization rules used for timing and addressing.
- Program memory data (PMD) and TPMA: on‑disc program memory information, temporary program memory area and rules for multi‑session media.
- Logical format and file system considerations: organisation of recorded data and compatibility with common optical file systems (references to UDF and ISO 9660 are normative).
- Normative annexes: examples and rules such as a standard disc definition, ATIP synchronization, and linking behaviour for recorders.
Applications and who uses IEC 62403:2005
IEC 62403 is practical for companies and professionals involved in optical media and consumer electronics:
- Optical disc drive / recorder manufacturers (firmware and hardware design)
- CD‑R/CD‑RW media manufacturers defining compliant substrates and pre‑groove features
- Consumer electronics designers (multimedia players, set‑top boxes) needing interchangeability
- Software and firmware developers implementing low‑level disc access, session management and write strategies
- Archive and data distribution solutions requiring higher capacity on CD media
Benefits include higher storage per disc, backward‑aware interchangeability, and defined error‑correction and session handling for robust consumer use.
