Title:
METHOD, APPARATUS AND SYSTEM FOR ACCESSING DISCONTINUOUS MEDIA TRACKS
Document Type and Number:
Japanese Patent JP2006196154
Kind Code:
A
Abstract:

To provide a method, an apparatus and a system for accessing discontinuous media tracks.

A storage medium 130 has one or more independently formed storage regions 210 thereon. Each storage region 210 may include a set of track segments 220. A memory 160 may be provided to store track offset information for each storage region 210. A mapping module 150 may collect track information, calculate a physical offset between adjacent storage regions, define a track 230, create a table 300, and store the track offset information in the memory. A tracking module 140 senses a position of a head relative to a centerline of a track segment 220 within a current storage region, accesses offset information, and aligns a storage head with a closely aligned track segment within a subsequent storage region.
