Servo writer, and write and inspection method of servo signal
View Patent ↗A servo writer of the invention writes a servo signal in a magnetic tape, reads and inspects the signal, and has a servo writer main body and a plurality of unit panels changeably loaded to a panel change unit provided at the main body according to a product class of the tape, wherein any of the unit panels has a servo write head for writing the signal in the tape and a write-sub-control mechanism for controlling a writing of the signal by the write head, wherein the write head and the sub-control mechanism write a predetermined signal in the tape, and wherein the main body has a signal main control mechanism for mainly controlling a writing of the signal in the tape by the write head, a servo read head for reading the signal written in the tape, and a signal inspection mechanism for processing and inspecting the signal.
1. A servo writer for writing a servo signal in a magnetic tape, and reading and inspecting the servo signal written, the writer comprising:
a servo writer main body; and
a plurality of unit panels changeably loaded to a panel change unit provided at said servo writer main body according to a product class of the magnetic tape where said servo signal is to be written,
wherein each of said plurality of the unit panels comprises a servo write head for writing the servo signal in said magnetic tape and a write-sub-control mechanism for controlling a writing of the servo signal by said servo write head, wherein said servo write head and said write-sub-control mechanism are configured so as to be able to write a predetermined signal in said magnetic tape according to the product class of said magnetic tape, and
wherein said servo writer main body comprises a servo signal main control mechanism for mainly controlling a writing of the servo signal in said magnetic tape by the servo write head of the unit panel selected in the panel change unit, a servo read head for reading the servo signal written in said magnetic tape, and a servo signal inspection mechanism for processing and inspecting the servo signal read.
2. A servo writer according to claim 1 , wherein any of said unit panels comprises a tape guide for regulating a position in lateral directions of a running magnetic tape, contacting said servo write head.
3. A servo writer according to claim 2 that can write a predetermined servo signal according to a product class of said magnetic tape, and read and inspect the written servo signal by an identifier provided at any of said unit panels and/or a switch mechanism provided at said servo writer main body.
4. A servo writer according to claim 1 that can write a predetermined servo signal according to a product class of said magnetic tape, and read and inspect the written servo signal by an identifier provided at any of said unit panels and/or a switch mechanism provided at said servo writer main body.
5. A servo writer according to claim 1 , wherein the servo signal main control mechanism sends information of every magnetic tape to the write-sub-control mechanism.
6. A servo writer according to claim 5 , wherein the write-sub-control mechanism generates the predetermined servo signal to be written in the magnetic tape based on the information sent by the servo-signal-main control mechanism.
7. The servo writer according to claim 1 , wherein the servo signal main control mechanism controls the write-sub-control mechanism.
8. The servo writer according to claim 1 , wherein the servo signal main control mechanism controls the generation of a servo pattern by the write-sub-control mechanism.
9. The servo writer according to claim 1 , wherein the servo signal main control mechanism sends a control signal to the write-sub-control mechanism that is independent of the product class of the magnetic tape.
10. A write and inspection method of a servo signal that uses a servo writer according to claim 1 and changes any of said unit panels according to a product class of a magnetic tape and to write a predetermined servo signal in the magnetic tape.
11. A write and inspection method of a servo signal that uses a servo writer according to claim 2 and changes any of said unit panels according to a product class of a magnetic tape and to write a predetermined servo signal in the magnetic tape.
12. A write and inspection method of a servo signal that uses a servo writer according to claim 4 and changes any of said unit panels according to a product class of a magnetic tape and to write a predetermined servo signal in the magnetic tape.
