Abstract: <P>PROBLEM TO BE SOLVED: To shorten rewind time from the end to the beginning of a magnetic tape.  <P>SOLUTION: A magnetic recording and reproducing apparatus has two operation mode of a mechanism, i.e. a first winding mode at a state that the magnetic tape 16 is wound to a rotary head cylinder 5 and a second winding mode that the magnetic tape 16 is not wound on the rotary head cylinder 5, is provided with a mode transition means 8 which transits the mechanism to either operating state of the first or second winding mode, a capstan motor 9 which performs fast forward or rewind of the magnetic tape 16 at either of the first or second winding mode and an end detection means 13 which detects the end of the magnetic tape 16. The mode transition means 8 stops a fast forward operation after transiting the operation mode to the second winding mode based on end detection from the end detection means 13 in the case of the fast forward operation by the first winding mode. Thus, mode transition from the first winding mode to the second winding mode becomes unnecessary in a rewinding operation by the second winding mode and the rewind time is shortened.  <P>COPYRIGHT: (C)2004,JPO

Title: Defect managing method for recording medium and real time data recording method
Inventor: KO JUNG-WAN
IPC: G11B20/12
Filed: 2002-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a recording medium for storing defect management information to record real time data, a defect managing method therefor, and a method for recording real time data. SOLUTION: The recording medium stores information representing use or non-use of linear replacement defect management in which a defective area on the recording medium is replaced with a spare area, in order to record the real time data in a recording area. Thus, while maintaining compatibility between the defect managing method and a defect managing method based on a current DVD-RAM standard, i.e., while allowing a report of the fact that there are blocks which are not linearly replaced, linear replacement is not performed when the real time data is recorded. Thus, the real time data can be recorded and/or reproduced.
