Title: Recording and reproducing apparatus and servo information recording method
Inventor: IZUMITANI YASUNORI
IPC: G11B5/596
Filed: 1995-01-30
Abstract: PURPOSE: To increase an index detection margin by a method wherein a true index pattern is recorded in a sector on a disk medium, a false index pattern is recorded in a sector which is continued to the sector and an index signal is output when a combined pattern is required. CONSTITUTION: True index pattern information 0 and servo information are recorded in a sector 33a for a track 32 on a disk medium, and pieces of false index pattern information 1, 2, 3 and servo information which contains them are recorded in sectors 33a-1 to 33a-3 , which are continuously adjacent to the sector 33a. Then, when an index is detected, an index signal is output from an index judging means when the combination 0, 1, 2, 3 of the pieces of index pattern information is the true index pattern information 0 and any of combination constituent parts is missing. When the combination of the pieces of index pattern information is used, an index detection margin is increased, and the recording time and the verification time of the servo information can be shortened.

Abstract: PURPOSE: To omit such processes as the disuse of the tape near the starting mark, the renewing of the mark and others by carrying out the tape running through detection of the tape starting and the defective identification signal.  
     CONSTITUTION: When the tape starting BOT mark of microprocessor part 1 is detected by magnetic tape unit 4, BOT signal 13 is received from BOT signal generation circuit 2 to perform the writing through unit 4. After this, the BOT enters error detection circuit 5 in the form of reading signal 14, and detection signal 15 is generated when the error is detected. And the set count value receives addition of only 1 at counter circuit 6, and at the same time retrial signal 16 is given to processor 1 and then to circuit 2. This action is repeated, and the repeating frequency is counted at circuit 6. When the repeating frequency exceeds the set value, detection signal 17 is applied to processor 1 as well as to defective signal identification signal generation circuit 7. Thus rewinding signal 19 is received to give rewinding to the tape, and then the writing is carried out at unit 4 after receiving identification signal 20 of circuit 7. In case the writing error occurs, demagnetization signal 22 is received to perform the demagnetization at unit 4. After end of the demagnetization, various types of identification signals 24 are generated from identification signal generation circuit 9.
