Abstract
Abstract A data recording method and apparatus records a record data (REC) with sequentially adding block numbers (BLNO) at every predetermined block, and the reproduction data (PB; RAW) obtained by simultaneous reproduction are monitored. When detecting an error of the reproduction data (PB; RAW), data is recorded again from the data having block number (BLNO) with the error occurrence. Therefore, a bit error rate will be enhanced remarkably.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
64 words
A data recording method comprising the steps of: recording (13) data (REC ) with sequentially adding block numbers (BLNO) at every predetermined block; monitoring (17, 51) a reproduction data (PB) obtained by simultaneously reproducing said reproduction data (RAW); and when an error of said reproduction data is detected, recording again said record data from the data having a block number of an error occurrence.
Claim 2
Dependent Claim
73 words
A data recording apparatus comprising: recording means (13) for recording data with sequentially adding block numbers (BLNO) at every predetermined block on tape (1 ) record medium; monitor means (17, 51) for monitoring said simultaneous reproduction data; control means (12, 52) for making said recording means record again, when said monitor means (17) detects the occurrence of an error, said record data from the data having a block number of the error occurrence.
Claim 3
Dependent Claim
34 words
A data recording apparatus according to claim 2, wherein said recording means (13) records obliquely said record data on a magnetic tape (1) as said tape record medium by means of rotary magnetic head.
